Summary: Green hydrogen, as a carbon-free renewable fuel, has the potential to reduce carbon emissions in various sectors. However, its generation is currently limited to water electrolysers, which are constrained by freshwater resources and critical raw materials. Photocatalysis and photoelectrocatalysis have been explored as alternative methods for green hydrogen generation, but the high costs hinder their commercial potential. The article discusses the possibility of using a novel photoelectrocatalytic process for simultaneous wastewater treatment, biomass reforming, and green hydrogen generation, which opens up opportunities for a circular economy and commercial viability.

Summary: This study proposes a method for continuous visible light-driven CO2 photoconversion to methanol using Cu2O/Mo2C/TiO2 heterostructures, which shows significant improvement in process performance. The heterostructures with 4 wt% of Cu2O exhibit superior methanol production rates, apparent quantum yield, and reaction selectivity compared to Cu2O-free Mo2C/TiO2 photocatalytic surfaces. The synergistic effect between Cu2O, Mo2C, and TiO2 in the heterostructures enhances charge separation and transfer, visible light absorption properties, and photocatalytic stability.
