Outdoor sunlight-driven scalable water-gas shift reaction through novel photothermal device-supported CuO x /ZnO/Al 2 O 3 nanosheets with a hydrogen generation rate of 192 mmol g −1 h −1

A new photothermal device is constructed by the Cr based selective light absorption film which can heat the 2D CuZnAl to 297 °C under 1 standard sun irradiation, leading to a 192 mmol g −1 h −1 of H 2 production rate from 1 sun irradiated WGS reaction.
