New photochemical diode artificial photosynthesis system doubles efficiency of solar water splitting

Green Car Congress

Researchers in Canada have demonstrated a new photochemical diode artificial photosynthesis system that can enable efficient, unassisted overall pure water splitting without using any sacrificial reagent. overall water splitting reaction. These free charges split water molecules into hydrogen and oxygen. … in neutral (pH?~?7.0)

IEEE Society Restores Electricity To a Nepali School

Cars That Think

Until recently, the residents of Melamchi, Nepal, cooked meals and heated water for bathing over a wood-burning stove. Schoolchildren didn’t have access to the Internet or reliable electric lighting for studying after dark. Kiani traveled in 2018 to Cairns, Australia, for the IEEE International Symposium on Industrial Electronics.

Japan team discovers novel photocatalyst composed of abundant elements; overturns conventional views

Green Car Congress

Scientists in Japan have shown that an oxyfluoride is capable of visible light-driven photocatalysis—i.e., converting solar energy to fuel energy using visible-light-absorbing semiconductor materials. The finding opens new doors for designing materials for artificial photosynthesis and solar energy research.
