Description We have providing new insights on the effect of support and alloy on the catalytic activity of Pt-based nanoparticles.We are developing a model to rational design nanocatalysts.

We have published recently a PCCP article on how to introduce a genetic genome to characterise the surface of metallic nanoparticles and providing the first approach to catalysis. We are preparing a more substantial paper to show how to model size-selected samples and their activity.

Two new numerical models have been proposed and published on ChemPhysChem and JCP. The kinetic Monte Carlo code presented in JCP is available on GitHub https://github.com/kcl-tscm/KMC_ORR

Our last contributions on ACS Cat. and on Nanoscale (2021 - just accepted) have shown the potential of the nanoCHE model we have developed. nanoCHE is a numerical tool which correlated structural changes to their oxidation or reduction activities.
Exploitation Route Eventually they could be used to fabricate better nanocatalyts and exploited in fuel cells applications.
If a geometrical approach to some chemical reactions will be accepted, this is going to be a quite breakthrough in the today approach to catalysis towards a more predictive science.

Description Stimulating the internal discussion and promoting new international collaborations. A new paper in collaborations with Wales' group (Cambridge) has been published and another between my group, Csanyi (Cambridge) and Bartok (Reading) has been submitted. Further I have published a outreach paper with Johnston: "Catalysts bit by bit", on http://researchfeatures.com/2017/11/01/designing-catalysts-bit-by-bit, which has potential to be used by a wider audience. Several activities at London schools.

We plan to put the code open-sources in two-three years once more potential and how to describe external enviroments will be implemented (our top priority). This will allow small compnies and academics to create a complete database for objects at the nanoscale not only with their peculiar structures but including their thermal stability and hints for investigating their physico-chemical properties.
