Investigation into photocatalytic degradation of gaseous cyclohexane in the circulated photocatalytic reactor

A series of surface catalytic reaction equations were developed to record the relationship between degradation efficiency and cyclohexane concentration in CPCR. The half-life of photocatalytic oxidation of cyclohexane was obtained according to Langmuir-Hinshelwoods (L-H) kinetic law. The results indicated that the degradation conversion data can be fitted by three linear functions at various cyclohexane concentration ranges, respectively, and having two points of intersection which divided the photocatalysis into three sections. These results were validated theoretically by the relationship between half-life and cyclohexane concentration.
