Engineering surface defects on two-dimensional ultrathin mesoporous anatase TiO2 nanosheets for efficient charge separation and exceptional solar-driven photocatalytic hydrogen evolution

Two-dimensional ultrathin mesoporous anatase TiO₂ nanosheets with engineered surface defects are fabricated via evaporation-induced self-assembly, solvothermal and hydrogenation, which exhibit excellent photocatalytic hydrogen evolution.
