摘要
Hydrogen production through semiconductor-based photocatalytic water splitting is an appropriate strategy to convert solar energy into hydrogen fuels[1].In recent years,metal-free elemental red phosphorus(RP)materials,including amorphous,fibrous,and Hittorfs phosphorus(HP)possessing moderate bandgap and bandstructure have been explored as potential visible-light-driven hydrogen evolution reaction(HER)photocatalyst[2].However,the slow charge migration capacity and sluggish surface reaction kinetics of RP materials have limited their HER efficiency to unsatisfactory levels.To overcome these limitations and improve the photocatalytic HER efficiency,various strategies,including building heterostructures,morphology control,and surface modification have been investigated[3].For instance,[001]-oriented HP nanorods decorated on polymeric carbon nitride exhibited excellent photocatalytic HER activity,which was attributed to accelerated photo-generated electron-holes transfer along the[001]direction of HP[4].In addition to enhancing the charge transfer ability by morphology regu-lation to allow more electrons to migrate to the surface to participate in HER,loading cocatalysts on RP surface to enhance HER kinetics is another effective strategy for altering HER activity[5].
