Michele Del Moro, from the research group ELCAT, presented his latest work on ‘Engineering of a flow cell for the photoelectrochemical conversion of CO2 to methanol’ at the ISE 73rd Annual Meeting under the topic of ‘Recent Advances in Photoelectrochemistry: catalysts, mechanisms, and applications’. He provided new insights in the influence of photocatalyst and reactor engineering on the performance of a photoelectrochemical system. These new insights are key for further innovation of the SYN-CAT project.
