New efficient, low-temperature catalyst for converting water and CO to hydrogen and CO2

Green Car Congress

Scientists in the US and China have developed a new low-temperature catalyst for producing high-purity hydrogen gas while simultaneously using up carbon monoxide (CO) via the water-gas shift (WGS) reaction. Its synergy with adjacent Mo sites in α-MoC can effectively activate water at low temperature. —Yao et al.

New molybdenum-coated catalyst produces hydrogen from water-splitting more efficiently; preventing the back reaction

Green Car Congress

Water-splitting systems require a very efficient catalyst to speed up the chemical reaction that splits water into hydrogen and oxygen, while preventing the two gases from recombining back into water. Therefore, inhibition of these back reactions is of paramount importance for photocatalytic water splitting.
