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 *** 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].
