摘要
环境污染与能源短缺已严重影响到人类的可持续发展。本文通过简单的葡萄糖水热和煅烧工艺,设计和构建具有优异性能的C/TiO2核壳光催化材料,并考察其光催化降解罗丹明B (RhB)的性能。采用SEM、TEM和XRD测试手段表征催化剂的微观形貌与结构。结果表明:可见光照射250 min,C/TiO2催化剂可降解98.5%的RhB,降解动力学速率常数达到0.0153 min−1。本工作为光催化高效降解有机污染物提供了新的思路。Environmental pollution and energy shortages have seriously affected the sustainable development of humanity. This paper designs and constructs C/TiO2 core-shell photocatalytic materials with excellent performance through simple glucose hydrothermal and calcination processes, and investigates their photocatalytic degradation performance of Rhoda mine B (RhB). The microstructure and morphology of the catalysts were characterized using SEM, TEM, and XRD testing methods. The results showed that under visible light irradiation for 250 min, the C/TiO2 catalyst could degrade 98.5% of RhB, and the degradation kinetics rate constant reached 0.0153 min−1. This work provides a new approach for the efficient photocatalytic degradation of organic pollutants.
