【 摘 要 】

tsThe multiple thermal treatments strategy is proposed for preparing the hollow oxygen-incorporated g-C3N4 nanosheets (OCN).Oxygen-adsorption creates a lot of defects to the formation of hollow and monolayered structure, while oxygen-doping reduces the band gap significantly.OCN exhibits stable and high photocatalytic hydrogen evolution with increased surface area, enhanced charge transport, and reduced band gap.
