摘要

石墨相氮化碳(g-C3N4)作为一种非金属半导体材料,具有低成本、合适的带隙和对可见光响应等特点,被广泛应用于光催化领域。在可见光的照射下,g-C3N4的空穴和电子对会与周围水和氧气反应产生活性氧来抑制细菌的生长。然而,g-C3N4的抗菌性仍面临着比表面积小、空穴-电子对易复合等问题。为克服这些缺陷,通过将 g-C3N4与其他纳米材料偶联或形成独特的结构来提高光催化性。根据对g-C3N4不同形貌、贵金属沉积、异质元素修饰和构筑异质结来进行分类,综述了国内外g-C3N4基纳米复合材料的制备工艺及抗菌性能的最新进展。

Abstract

Graphite carbon nitride (g-C3N4),a non-metallic semiconductor material,widely used in the field of photocatalysis due to its low cost,suitable bandgap and response to visible light.Their holes and electron pairs can react with surrounding water and oxygen,generating reactive oxygen species and inhibiting the growth of bacteria under visible light irradiation.However,the antibacterial properties of g-C3N4 still face some problems such as small specific surface area and easy complexation of hole-electron pairs.To overcome these shortcomings,g-C3N4 enhances photocatalysis antibacterial properties by coupling with other nanomaterials or forming unique structures.The g-C3N4 is classified according to different morphologies,noble metal deposition,heterogeneous element modification and construction of heterojunction.By the end,a review on the preparation technology and antibacterial properties of g-C3N4 based nanocomposites was presented.
