Will industrial-scale photocatalysis see the light of day?

90% of our commodity chemicals and fuels are made from thermocatalysis industries driven by heat or grid power. In the context of carbon-neutral society, sunlight-driven photocatalysis is an ideal alternative to thermocatalysis especially for CO2 and H2O utilization. However, how … Continue reading
