摘要
概述光催化氧化脱硫脱硝的研究进展,探讨光催化脱硫脱硝的特性及机理,对光催化氧化同时脱硫脱硝的可行性进行分析,提出了提高催化剂的光量子产生率的途径、光吸收范围向可见光扩展的方法以及如何设计简单高效的光反应器等目前亟待决解决的几个问题,为光催化氧化脱硫脱硝的实际应用提供了理论基础。
The advance on removal of SO2 and NOX by TiO2 photocatalyst was reviewed, characteristics and reaction mechanism of photocatalytic oxidation was discussed, feasibility of simultaneous desulfurization and denitrification was analyzed. Some problems including quantum yield of photocatalytic reaction, extending light absorption into visible light range and design of photocatalytic reactor which need to be solved in current studies were proposed, which will provide theoretical basis for practical application.
