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

Abstract

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