摘　　要：随着纺织业的快速发展,纺织业污水处理成为亟待解决的环境问题,未经处理净化或未净化彻底的有机染料废水的排放造成水体污染,严重破坏生态平衡,对人类赖以生存的生活环境带来巨大损失。ZnO因其高光敏性、晶形可控和优异的光电催化活性,使其在催化降解水中有机污染物方面表现出独特的优势。但是单一ZnO材料存在光生载流子复合几率高、太阳光利用率低等不足,限制了其在实际应用中的效果。为进一步提高ZnO的光催化性能,概括讨论了ZnO作为光催化剂的改性方法,并详细讨论了ZnO/g-C_(3)N_(4)纳米复合材料在光催化领域的研究进展。复合后的光催化剂具有更小的带隙,在可见光区域具有更宽的光响应范围且能够通过异质结构促进电子-空穴的有效分离,从而提高在可见光下的光催化性能。With the rapid development of the textile industry,the treatment of wastewater from the textile industry has become an urgent environmental issue that needs to be addressed.The discharge of untreated or inadequately treated organic dye wastewater leads to severe water pollution and disrupts the ecological balance,causing significant losses to the living environment that humanity depends on for survival.ZnO has shown unique advantages in catalytic degradation of organic pollutants in water,due to its high photosensitivity,controllable crystal shape and excellent photocatalytic activity.However,the single ZnO material suffers from high recombination rates of photogenerated charge carriers and low utilization rates of solar light,which are significant drawbacks.This limits the effectiveness of ZnO in practical applications.To further enhance the photocatalytic performance of ZnO,this paper provides a general discussion on the modification methods of ZnO as a photocatalyst and discussed the research progress of ZnO/g-C_(3)N_(4) nanocomposites in the field of photocatalysis.The ZnO/g-C_(3)N_(4) photocatalyst exhibits a smaller band gap,which results in a broader light response range in the visible light region,and can promote the effective separation of electrons and holes through its heterostructure,thereby enhancing the photocatalytic performance under visible light.
