石墨相氮化碳（g-C3N4）作为一种可见光响应型半导体材料,具有稳定性高、廉价、结构与性能可调控性高等优点。随着绿色环保、无二次污染的光催化技术的不断发展,g-C3N4光催化剂逐渐成为环境与能源科学领域的研究热点。而单一的g-C3N4存在光激发电子-空穴复合过快、可见光的利用率低等缺陷导致其光催化效率较低。在众多的改性方法中,异质耦合被认为是提高g-C3N4光催化性能的有效方法。近年来,研究者通过将不同的无机半导体、贵金属、碳材料等与g-C3N4进行异质耦合,提高了光电子在光催化体系中的转移效率,拓宽了g-C3N4基光催化剂对可见光的吸收范围,并且增强了g-C3N4催化剂稳定性与结构的可调控。...

Graphite carbon nitride (g-C3N4) is a visible light responsive semiconductor material with the advantages of high stability, low cost, high adjustability of structure and property. With the continuous development of green and non-secondary pollution photocatalytic technology, g-C3N4has gradually become a research hotspot in the field of environment and energy science. Nevertheless, the bare g-C3N4 exhibits relatively low photocatalytic efficiency, which is due to the rapid recombination of photogenerated charge carriers and low visible light ut...
