两种合成方法制得g-C3 N4的光催化性能
Effect of two synthetic methods on photocatalytic properties of g-C3N4
摘要
Abstract
This paper is devoted to investigating how to overcome the notorious effect of the synthetic conditions on the photocatalytic performance of Graphite carbon nitride ( g-C3 N4 ) —a polymeric semicon-ductor which has become the hotspot in field of photocatalytic materials. This investigation consists of pre-paring ecarbon nitride by melamine at different temperatures under the condition of semi-closing and ar-gon shielding, respectively;characterizing its structural properties by XRD, FT-IR, UV-Vis and DRS;and evaluating its photocatalytic performance by SPS and photocatalytic degradation of phenol. The results show that, exposed to the rising synthetic temperature, the g-C3 N4 ’ s prepared under the semi-closing condition, exhibits a narrowed band gap, a red-shift in spectral absorption range, and no obviously weak-ened photocatalytic activity;subjected to the rising synthetic temperature, the g-C3 N4 ’ s prepared under the semi-closing condition, exhibits a significantly narrowed band gap, a greater red-shift in spectral ab-sorption range, and a remarkably weakened photocatalytic activity;and the synthesis of the g-C3 N4 with a higher sunlight utilization rate, a higher electrical conductivity and a higher photocatalytic activity is pos-sible with the condition of lower temperature and argon shielding.关键词
