Abstract

CeO2 nanotube with improved catalytic properties has been synthesized by a simple precipitation method using P123 triblock copolymer as surfactant. The prepared samples were characterized by X-ray diffraction, Scanning electron microscopy and BET surface area analysis. The activity of the material in catalytic ozonation degradation of organic pollutants in textile wastewater was investigated. The results showed that the presence of P123 could improve the crystallization of CeO2 particles and slightly enlarge their specific surface area. The catalytic efficiency of the as-prepared CeO2 nanotube with P123 adjusted is higher than that of CeO2 nanotube with urea treatment. The spent catalyst could be recycled with only slight decline in catalytic activity.
