Abstract

Abstract

The mechanisms of nanometer TiO₂ photodegrading HCHO were summarized. The discussion focuses upon the influence of nanometer TiO₂ content, crystal dimension, crystal type in the emulsoid and reaction temperature on the property of nanometer TiO₂ photodegrading HCHO. The influence of HCHO molar consistency and degradation-reaction time on the photodegradation rate of HCHO are discussed.
