| Abstract: | Graphite-like carbon nitride (g-C3N4) is a free of metals semiconductor which comprises easy preparation, low prices, rich content and super physical and chemical properties, in addition, it can absorb the visible light due to its narrow bandgap, and hence, the g-C3N4 is becoming a research hotspot. However, the drawbacks of low specific surface area, high recombination rate of photoelectrons and holes and poor absorbed visible light which was the researchers are trying to resolve. This paper reviews the modified strategies of g-C3N4, which including non-metal doping, surface defects, noble metal modifying and constructed heterostructure composite etc. The enhanced of photocatalytic performances are analyzed and the prospects for future investigations of g-C3N4 are proposed. |
