Abstract

A rather simple model was developed, which predicted a hyperbolic relation between the photocatalytic reaction rate and solution conductivity. Experimental validation was performed using methyl orange as a model pollutant and titanium dioxide as a photocatalyst. The experiments, conducted with three different salts confirm the hyperbolic correlation between the photocatalytic degradation rate and solution conductivity. The results have evinced this correlation, albeit the model ignores crucial factors, such as the role of one of the two types of charges generated during light absorption and the chemical decomposition pathway. In addition, the experimentally derived hyperbolic function displays a positive shift along the ordinate.

溶液电导率是决定光催化反应速率的一个因素
建立了一个相当简单的模型,该模型预测光催化反应速率与溶液电导率之间存在双曲线关系。以甲基橙为模型污染物,二氧化钛为光催化剂,进行了实验验证。使用三种不同盐类进行的实验证实了光催化降解率与溶液电导率之间的双曲线关系。尽管模型忽略了一些关键因素,例如光吸收过程中产生的两种电荷之一的作用和化学分解途径,但实验结果证明了这种相关性。此外,实验得出的双曲线函数显示出沿纵坐标的正向移动。
