Photocatalysis is one of the most effective ways to solve environmental problems by solving pollutants. This article designed and prepared a conjugated system of 2,4,6-triaminopyrimidine-g-CN (TAP-CN) to modify ZnO NWs. We systematically studied the photocatalytic performance of ZnO NWs modified with different ratios of TAP-CN. The results showed that 9 wt% TAP-CN-30/ZnO NWs had the best degradation effect on Rhodamine B dye. The degradation rate was 99.36% in 80 min. The excellent degradation performance was attributed to the TAP-CN conjugated system promoting photo-generated charge transfer. This work provided guidance for designing efficient composite catalysts for application in other renewable energy fields.
光催化是通过解决污染物来解决环境问题的最有效方法之一。本文设计并制备了2,4,6-三氨基嘧啶-g-CN（TAP-CN）共轭体系以修饰ZnO纳米线。我们系统地研究了不同比例TAP-CN修饰的ZnO纳米线的光催化性能。结果表明，9 wt% TAP-CN-30/ZnO纳米线对罗丹明B染料具有最佳降解效果。80分钟内降解率为99.36%。优异的降解性能归因于TAP-CN共轭体系促进光生电荷转移。这项工作为设计用于其他可再生能源领域的高效复合催化剂提供了指导。
