Nanostructured Pd hydride microelectrodes: in situ monitoring of pH variations in a porous medium.
in Analytical chemistry
Description | The project has successfully demonstrated that nanostructured Pd hydride microelectrodes could be used to monitor the evolution of pH during the carbonation of lime exposed to carbon dioxide. |
Exploitation Route | In situ monitoring of pH changes during the carbonation of building mortars and cements. The electrodes investigated in the project could be further developed to produce a pH sensor for the construction industry. A year or so after the end of the project the team was contacted by a company to discuss a feasibility study on the application of nanostructured PdH pH microelectrodes on their products. In the end the company decided not to go ahead with the study. |
Sectors | Construction |
Description | The project has led to several publications and presentations at conferences. Following a conference presentation the team was contacted by a company to undertake a feasibility study. After discussion with the company they decided not to go ahead with the feasibility study. |

Results and Impact | The oral presentation attracted questions from industrial participants and has since led to a request for a feasibility study. Following the oral presentation we have been contacted by an industry to conduct a feasibility study on their products using eh methodology we developed during the research project. |

Results and Impact | This poster presented at the 62nd international meeting of the International Society of Electrochemistry, Prague, Aug. 2012 won the best poster prize. The poster describes the development and characterisation of nanostructured microelectrodes to measure pH changes during the carbonation processes in lime based mortars. As a result Marra Serrapede was invited to present a lecture at the International Meeting on Scanning Electrochemical Microscopy the following year |

Results and Impact | Marra Serrapede gave a 20 min oral presentation at the 7th international workshop on Scanning Electrochemical Microscopy (SECM) held in Ein Gedi, Israel, between the 17th and 21st of February 2013. This congress, held every 2 or 3 years, brings together the world experts in SECM and related techniques. It was attended by over 70 participants from 22 nations; half from Europe, the remainder coming from Canada, the USA, South Africa, China, Japan, Ukraine. Mara presented new results which highlight the role of oxygen when performing in-situ pH measurements with palladium hydride microelectrodes. She also presented a theoretical approach which explains these results and quantify the impact oxygen has on the pH measured in-situ. This event gave us the chance to showcase our work to the research community |
