CeO 2 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 CeO 2 particles and slightly enlarge their specific surface area. The catalytic efficiency of the as-prepared CeO 2 nanotube with P123 adjusted is higher than that of CeO 2 nanotube with urea treatment. The spent catalyst could be recycled with only slight decline in catalytic activity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
