摘要

摘要: 光催化作为一项绿色、高效的污染物治理技术,其传统光催化材料缺少对全光谱中红外光区的利用,会在一定程度上造成资源的浪费,限制了污染物降解能力上限。因此,利用WO_3-x光催化降解甲氧苄啶(TMP),探索了不同光谱下的降解性能以及在最优降解条件下的降解机理。结果表明:黑暗和红外光条件下,TMP几乎未发生降解。全光谱条件下TMP的降解率相较于紫外-可见光提高44.8%。2种体系中WO_3-x光催化反应降解TMP的机理较为相似,O^-₂·和H₂O₂是发挥主要作用的活性物种。在降解过程中,大量的活性自由基在催化剂表面产生,然后进入均相体系,促进TMP降解;同时,WO_3-x对全光谱中红外光区间段的有效吸收展现出优异的降解能力。此外,温度在反应体系中并不是提升降解率的主导因素。

Abstract: Photocatalysis is a green and efficient pollutant treatment technology. The lack of utilization of the mid-infrared light region by traditional photocatalytic materials causes a waste of resources and limits the upper limit of pollutants' degradation efficiency. This study used photocatalytic degradation of TMP based on WO_3-x to explore the degradation performance under different spectra and the degradation mechanism under the optimal degradation condition. The results showed that TMP was hardly degraded under dark and infrared light conditions. Compared with UV-visible light, the degradation of TMP under full spectrum conditions was increased by 44.8%. The mechanism of TMP degradation by WO_3-x photocatalytic reaction in the two systems was similar, and O^-₂· and H₂O₂ were the active species that played the main role. During the degradation process, a large number of active radicals were generated on the catalyst surface and then entered the homogeneous system to promote the degradation of TMP. At the same time, temperature was not the dominant factor in improving the degradation rate in the reaction system, because WO_3-x exhibited excellent degradation ability due to the effective absorption of the mid-infrared light region of the full spectrum.
