TiO_(2)-based Photocatalysts for Photocatalytic Degradation of Organic Pollutants

不同行业产生的有机化合物会产生一系列有问题的废水污染物。由于其优异的特性,包括无毒、高光催化降解能力以及优异的热和化学稳定性,TiO_(2)基光催化剂是具有优异吸收性能的新型材料。然而,TiO_(2)在有机废水处理中的应用仍然存在挑战,例如颗粒聚集、质量转移受限、亲和力差、能带宽和回收困难。因此,需要对TiO_(2)基光催化剂进行更多的设计和优化,从而以更低的成本达到更高的去除效率。本文主要对影响TiO_(2)基光催化剂活性的各种参数如TiO_(2)的结构、pH值、颗粒大小、掺杂剂和添加剂的引入进行了深入的研究使其得到进一步的研究和发展。

Organic compounds produced by different industries create a range of problematic wastewater contaminants.Due to its excellent properties,including nontoxicity,high photocatalytic degradation ability,and excellent thermal and chemical stability,TiO_(2)-based photocatalysts are novel materials with excellent absorption properties.However,the application of TiO_(2) in organic wastewater treatment still has challenges,such as particle aggregation,limited mass transfer,poor affinity,wide energy band,and difficulty in recycling.Therefore,more design and optimization of TiO_(2)-based photocatalysts are needed to achieve higher removal efficiency with lower cost.In this paper,various parameters affecting the activity of TiO_(2)-based photocatalysts,such as the structure of TiO_(2),pH value,particle size,and the introduction of dopants and additives,have been intensively studied to enable further research and development.
