主 题:Red phosphorus Cobalt phosphide Heterostructure Photocatalytic hydrogen evolution
摘 要:Red phosphorus(RP) is a promising visible-light-driven semiconductor for photocatalytic hydrogen evolution,but the activity is restricted due to the rapid charge carrier recombination and sluggish surface reaction ***,cobalt phosphide(CoP_(2)) modified RP heterostructure was developed by in situ phosphorization of cobalt oxide from phosphorus *** tuning the amounts of CoP_(2) in the heterostructure,the optimized hybrid exhibited a HER rate reaching 11.79 μmol h^(-1) under visible light illumination,which is 3.5 times higher than that of the RP with Pt as *** was experimentally indicated that the intimate interaction between CoP_(2) and RP gave rise to improved visible light absorption and accelerated photogenerated electron-holes ***,the CoP_(2) as a noble-metal-free cocatalyst could promote the surface hydrogen evolution reaction,which synergetic benefited the photocatalytic hydrogen production activity.
