In situ construction of a 2D CoTiO3/g-C3N4 photocatalyst with an S-scheme heterojunction and its excellent performance for CO2 reduction

The CoTiO 3 /g-C 3 N 4 heterojunction showed a stronger redox potential than g-C 3 N 4 . Furthermore, the use of triethanolamine as a h + /–OH and e − sacrificial agent significantly enabled the efficient utilization of photogenerated electron–hole pairs.
