Elizabeth Bay gave an oral presentation entitled Understanding of photocatalytic reduction of carbon dioxide in context of reactor design at the 3rd UK Solar Fuels Network Symposium held here at Heriot Watt. It is unique work that has been well received. Dr Federico M Pesci from Imperial College London commented “The second talk I particularly enjoyed was given by Elizabeth Bay from Heriot-Watt University (PG symposium, 19th of January). She raised a really interesting point, showing how different scientific communities use various parameters to define the efficiency of solar fuel reactors, leading to misinterpretations when comparing the reported efficiencies of practical devices. A standardisation of these parameters could in fact be beneficial in order to facilitate the comparison between several reactors and define a communal efficiency target.” This was found through the Solar Fuels Network Newsletter with responses from SFN travel bursary winners.
