Mathematically-designed graphene has improved electrocatalytic activity for hydrogen production

Green Car Congress

An international research group has improved graphene’s ability to catalyze the hydrogen evolution reaction, which releases hydrogen as a result of passing an electronic current through water. The graphene-based electrocatalyst was then used to enhance the release of hydrogen during electrolysis. Wakisaka, Y.

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.
