The significance of the oxidation state of gold in heterogeneous catalysis

Abstract
We aim to construct a detailed picture of the processes, intermediates and active sites involved in the hydrochlorination of ethyne over gold chloride nanoparticles supported on carbon surfaces. The hydrochlorination of ethyne provides an alternative route to vinyl chloride which at present is manufactured by a two step process involving the oxychlorination of ethene to form 1,2-dichloroethane followed by cracking. Vinyl chloride is polymerised to polyvinyl chloride (PVC) an important polymer with widespread applications in the construction and electronics industries. Sixty years ago vinyl chloride was almost exclusively made by the direct hydrochlorination of ethyne, which derives from coal, over a mercury chloride catalyst but the availability of inexpensive ethene from oil led to a change of manufacturing route despite the lower yields, lower product purity and higher costs for waste treatment. Now, dwindling oil reserves and increasing environmental awareness is dictating a search for to the alternatives to the oxychlorination route. The safety and environmental issues posed by HgCl2 prevent a return to the former catalyst but Hutchings and co-workers have proven that gold supported on carbon can be a viable alternative. Our project will inform the development of such catalysts but will also provide an important new window on gold catalysis.
Whilst catalysis by gold nanoparticles is an established phenomenon particularly in relation to selective oxidation processes, the key points of the active site and the reaction mechanism remain very controversial despite extensive work. Different researchers have separately emphasised the importance of different aspects of gold catalysts for example: the size of the gold particles; the interface between the gold and the support and the oxidation state of the gold. Fierro-Gonzalez & Gates ascribe this controversy to the fact that attention has largely focussed on mechanistic studies of CO oxidation and suggest that this experimentally appealing reaction is not as straight forward as it appears. They recommend that more diverse systems be investigated at a fundamental level if further progress is to be made in understanding the nature of the active site in gold catalysis and thus provide direction to the development of better gold catalysts. Au/C catalysts have received remarkably little attention from the surface science community (in contrast to the gold/oxide catalysts) and a study of the fundamental chemistry underlying this system therefore offers the prospect not only of advancing the development of an important future catalyst but also of shedding new light on some of the fundamental principles of gold catalysis.
A powerful combination of surface spectroscopy, surface microscopy and surface kinetic methods applied in conjunction with computational chemistry will be focussed on identifying and characterising the active states of gold in ideal models of the hydrochlorination catalyst. However, in practice, the Au/C hydrochlorination catalyst consists of a high area activated carbon exhibiting a variety of functional groups at the surface which may influence the deposition and stability of the adsorbed gold halides. To address this issue the project involves three separate parallel strands with studies of gold deposited from aqueous solutions on modified HOPG and activated carbon under ambient conditions providing the bridge between model surface science/computational studies of gold halides on HOPG and the practical catalysis.

Planned Impact
Gold catalysis is increasingly seen as an important technology for the future of the catalysis industry. Our focus will be on gold halides at the nanoscale a novel area of exploration and one which will provide new insights into the fundamental principles of gold catalysis. An improved understanding in this area will lead to a better framework of knowledge on which the design of new and improved catalysts can be based, thus the most obvious area of impact of the proposed work will be the commercial catalytic community. The surface chemistry of chlorine is also of direct interest since the recycling of chlorine by the chemical industry is currently very poor; almost a third of the chlorine used ends up as difficult to dispose of waste. More efficient use of chlorine would have a significant effect on the costs and environmental impact of industry and there is therefore considerable interest in developing new processes involving HCl instead of Cl2.
More generally, the interface between surface, nanoparticle and a gas is an area of broad technological interest. The research team involved in this proposal all have good links with industry and the majority of these collaborations relate to the area of nanoscience and surfaces. These links will provide a rapid conduit for the propagation of information and skills in surface and nanoscience to the industrial science base with a resulting impact that is much more far reaching than that of the specific gold/chlorine topic. Funding the project will also enable the group to maintain (and upgrade) its unique combination of equipment which facilitates such collaborations and allows the training of students in practical surface and nanoscience; the "research led teaching" philosophy at Cardiff leading to extensive exposure of our undergraduates to the tools and concepts used in the research of the department. More specifically the project will result in the training of a postdoctoral worker, a postgraduate student and several graduates (see the "Pathways to Impact" document) generating a range of versatile and creative scientists skilled in this technologically important area; the vast majority of our students eventually progress to careers in industry or teaching and thus propogate their knowledge, skills and enthusiasm for nanoscience to the wider community.
Finally, the extensive outreach activities of the team will benefit the general public by providing a range of stimulating activities demonstrating the concepts, importance and excitement of nanoscience.

Description | High surface area carbon is used as a support for many types of catalyst, but there are many kinds of carbon and these can have huge effects on the catalysts. Because carbons can be very complex they are relatively poorly understood. Our work has tried to improve understanding of the fundamental properties of a carbon that affects the catalyst that is formed upon it. We have established methods of producing very well defined carbon surfaces (graphite) with a single type of functional group present specifically hydroxides (-OH) and ketones (-C=O ). We established the identity of these groups using a chemi-selective derivatization method which has not been used on graphite previously. This then allowed us to explore the influence of these specific groups on the deposition of gold onto the surface from solution and latterly to investigate palladium adsorption - an aspect of the work that continues. These experiments were supported by computational chemistry which explored the formation of functional groups on graphite surfaces and their interaction with gold from solution. Different acid treatments of the carbons appears to lead to different types of oxygen groups and we are now investigating how that affects the catalysts that subsequently develop. Hydroxyls encourage nucleation of gold onto carbon surfaces and also lead to reduction, whereas carbonyl groups are less promoting towards nucleation and form fewer but larger gold clusters on the surface. This work will contribute to a better understanding of the formation of catalysts consisting of gold supported on carbon a topic of great interest at the moment because of gold's unusual catalytic properties and the development of a novel gold/carbon catalyst for the hydrochlorination of ethyne to make vinyl chloride that is the monomer used to create the polymer PVC. |
Exploitation Route | The approach of studying gold deposition under ambient conditions using surface science methods has general applicability to the study of the formation of many other catalysts. We would like to extend the work to monitor the deposition of materials insitu using AFM in solution. |

Description | In addition to the new knowledge that we have been able to provide to the scientific community the impact of the grant has been in two ways: firstly the people who have received training in catalysis and nanoscience and secondly the general public through the outreach events that the team have organised. For the first point we have not only employed 2 PDRA's in the course of the project but also financed two PhD students. In addition, we have taken on 4 undergraduate students and paid them to work with the research team over the summers of 2012, 13, 14 and 15 (8 weeks work each, funded by the University and also by the Royal Society of Chemistry, they have all been included in published papers, two of them are now undertaking PhD's) and 5 undergraduate project students, two of whom are now studying for PhD's and one, who finishes this year, intends to apply for a PhD in this area. We have also hosted two Nuffield funded summer projects (6 weeks) as work experience for A-level students and several week long work experience sessions for A-level students. For the second point we have done a lot of outreach work involving presentations to various groups including the Monmouth U3A and Swansea Chemistry society. Perhaps the high points though have been the exhibit that we staged for the Royal Society Summer Science show in July 2014 (attracting ~ 15,000 visitors), the Diamond Light Source Open day in July 2015 and the Royal society sponsored Summer Science School for St Pauls' Trust in August 2015. This March (19th) we have been invited to the Royal Society to put on our exhibit again for an open day at their headquarters. In 2016, for the Manchester Science Show, we staged a reprise of the exhibit we put up for the Royal Society's Summer Science festival in 2014. |
