Abstract
A ZrO2 catalyst was prepared through a simple electrochemical method which resulted in superior photoactivity toward dyes and phenolic compound degradation. An amount of 0.4 g L−1 of ZrO2 catalyst was found to be an optimum dosage for 10 mg L−1 dye and phenol solution, which resulted in nearly complete degradation of dyes and phenol solution (more than 80%) after 1 h of contact time at pH 9 under fluorescent light irradiation. The degradation followed pseudo first–order kinetic rationalized Langmuir–Hinshelwood model. An excellent photo-activity toward degradation of dyes and phenol in aqueous solution promises the ZrO2 catalyst to be used in textiles industry wastewater treatment and also other applications.
