ZnTiO_(3)/TiO_(2)复合光催化材料研究进展

Research progress on ZnTiO_(3)/TiO_(2) photocatalytic composite material

为提高TiO_(2)光催化性能,对其进行半导体复合改性是有效的方法。具有钙钛矿结构的ZnTiO_(3)与TiO_(2)复合形成异质结,能有效地抑制光生电子与空穴的复合,提高光催化性能。总结了溶胶-凝胶法与水热法制备ZnTiO_(3)/TiO_(2)复合光催化材料的研究进展;并进一步综述了ZnTiO_(3)/TiO_(2)光催化剂的最新改性研究成果。

Semiconductors coupling modification is an effective method to improve the photocatalytic performance of TiO_(2).ZnTiO_(3)with perovskite structure forms heterojunction with TiO_(2),which can effectively inhibit the recombination of photogenerated electrons and holes,and improve the photocatalytic performance.The research progress on ZnTiO_(3)/TiO_(2)photocatalytic material prepared by sol-gel method and hydrothermal method was summarized,and reviewed the latest research results of ZnTiO_(3)/TiO_(2)photocatalyst.
