基于后功能化工艺修饰类石墨相氮化碳及其光催化产氢性能研究
Post-functionalization of graphitic carbon nitride for highly efficient photocatalytic hydrogen evolution
摘要
Abstract
In this work we report the feasible modification of graphitic carbon nitride(g-C3N4)polymer through a post-functionalization progress.The resultant photocatalyst exhibits boron doping and mesoporous structure with a high surface area of 125 m2/g,leading in an increased surface activity for photocatalytic water splitting reaction.X-ray diffraction,X-ray photoelectron spectroscopy,PL emission spectra and UV-Vis spectra were used to detect the properties of as-prepared samples.Based on X-ray photoelectron spectroscopy analysis,boron is proposed to dope in the g-C3N4 lattice.Optical studies indicated that boron doped g-C3N4 exhibits enhanced and extended light absorbance in the visible-light region and a much lower intensity of PL emission spectra compared to pure g-C3N4.As a result,boron doped g-C3N4 shows activity of 10.2 times higher than the pristine g-C3N4 for photocatalytic hydrogen evolution.This work may provide a way to design efficient and mesoporous photocatalysts through post modification.关键词
