Breakthrough catalysts for H2 production published in South China Morning Post

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.
