【摘要】：聚合物半導體石墨相氮化碳(g-C_3N_4),作為一種非金屬可見光光催化劑,在太陽能轉(zhuǎn)化和環(huán)境保護方面有著巨大的潛在應用。由于其具有高物理化學穩(wěn)定性及獨特的光捕獲性能,可以直接將低密度的太陽能轉(zhuǎn)化為高密度的化學能,或直接降解有機污染物,因此,g-C_3N_4制備和性能的研究引起了國內(nèi)外研究人員的廣泛關注。研究表明,用不同方法和化學工藝對氮化碳在結構上進行改進,可以獲得新的理化性質(zhì),提高氮化碳的光催化效率,篩選出在特定反應下高效率的氮化碳結構。硬模板法制備g-C_3N_4納米材料,可以有效地提高其表面積,促進光捕獲和光生電子傳遞,進一步提高光催化效率。今對硬模板法制備氮化碳及研究現(xiàn)狀進行了詳細介紹,同時對g-C_3N_4光催化劑的發(fā)展趨勢進行了展望。
[Abstract]:Polymer semiconductor graphite phase carbon nitride g-C3N4D, as a non-metallic visible light catalyst, has great potential applications in solar energy conversion and environmental protection, due to its high physical and chemical stability and unique photocapture properties. Low density solar energy can be directly converted into high density chemical energy, or organic pollutants can be directly degraded. Therefore, the preparation and properties of C3N _ 4 have attracted wide attention from researchers both at home and abroad. By improving the structure of carbon nitride by different methods and chemical processes, new physical and chemical properties can be obtained, the photocatalytic efficiency of carbon nitride can be improved, and the structure of carbon nitride with high efficiency under specific reaction can be screened out. G-C _ 3N _ 4 nanomaterials are prepared by hard template method. It can effectively increase the surface area, promote phototrapping and photoelectron transfer, and further improve the photocatalytic efficiency. In this paper, the preparation of carbon nitride by hard template and its research status are introduced in detail. At the same time, the development trend of g-C _ 3N _ 4 photocatalyst is prospected.
