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.
