This benchmark work was carried out by an international team of UCL and Yunnan University in China. H2 production on demand is highly attractive, such as for H2 vehicles. A copper single-atoms (SA) /TiO2 catalyst reported by the team on Nature Communication (2022, https://doi.org/10.1038/s41467-021-27698-3 ) shows the excellent H2 evolution rate of 101.7 mmol h-1 g-1 under light irradiation, which is much higher and cheaper than the benchmark catalyst platinum single-atom (PtSA)/TiO2 , in addition to the stability as proved after storing 380 days in laboratory. More importantly, the optimized sample exhibits an apparent quantum efficiency of 56% at 365 nm, a significant breakthrough in this field.
