摘要

Abstract

Hydrogen production by photolysis of water by sunlight is an environmentally-friendly preparation technology for renewable energy. Graphitic carbon nitride (g-C

)

despite with obvious catalytic effect

is still unsatisfactory for hydrogen production. In this work

phosphorus element is incorporated to tune g-C

's property through calcinating the mixture of g-C

and NaH

sacrificial agent and co-catalyst also been supplied to help efficient photocatalytic hydrogen production. Phosphorus (P) doped g-C

samples (PCN-S) were prepared

and their catalytic properties were studied. X-ray diffraction (XRD)

X-ray photoelectron spectroscopy (XPS)

scanning electron microscopy (SEM) and ultraviolet diffuse reflection (UV-DRS) were used to study their structures and morphologies. The results show that the reaction rate of PCN-S is 318 μmol·h

-1

·g

-1

which is 2.98 times as high as pure carbon nitride nanosheets (CN) can do. Our study paves a new avenue

which is simple

environment-friendly and sustainable

to syn

thesize highly efficient P doping g-C

nanosheets for solar energy conversion.
