摘 要:Defect engineering greatly enhances the cat-alytic activity of transition metal semiconductor ***,localized surface defects engineering has been intensively researched,but it still remains challenges on how to tilt the balance to the controllable construction of surface defects rather than bulk ***,we report a facile room-temperature solution processing strategy on(001)facet exposed anatase TiO_(2) nanosheets(ATO),in which localized defects are generated on the surface selectivity with high *** achieve the aspect,lithium-ethylenediamine(Li-EDA)treatment is carried out on(001)facet exposed ATO under a mild *** optimized sample exhibits outstanding photocatalytic H_(2) production rates of 9.28 mmol·g^(-1)·h^(-1) with loading 0.5 wt%Pt as co-catalyst(AM 1.5),which is nearly 7.5 times higher than that of the pristine *** defect engi-neering strategy of ATO photocatalyst will spark the ideas for the defects engineering and semiconductor photocata-lyst,which is with important application prospect in solar energy conversion,including hydrogen generation and carbon dioxide reduction.
