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. In order to achieve high WGS activity at low temperature, we searched for catalysts that could dissociate water efficiently and reform the generated oxygen-containing species (reaction of surface oxygen or hydroxyl with CO*) at low temperature.
