Bjorn Joos and Nele Debusschere, from the research group DESINe, presented their posters at the MATSUS conference on ‘Materials for sustainable development’ in Valencia, Spain. The poster of Bjorn Joos was awarded for the best poster presentation in the category of ‘Advances in inorganic thin film semiconductors for solar energy conversion: From photovoltaics to solar fuels’. Thanks to their new insights, we now have new synthesis procedures  and insights for electrocatalysts and photocatalysts, which will be beneficial for further steps in the understanding of new photocatalysts for the SYN-CAT project.
