Fenton-like catalytic degradations of neutral red in water using cerium oxide polishing powder

Abstract

Cerium (IV) oxide, CeO2, is one of the most reactive rare-earth oxide, which has been attracting great interest in the past decade owing to its widespread variety of environment and energy-related applications including solid-state electrolytes for electrochemical devices (Mogensen et al. in Solid State Ionics 129:63–64, 2000), catalysts for three-way automobile exhaust systems (TWC) (Nikolaou in Sci Total Environ 235:71, 1999), polishing agents for chemical–mechanical planarization (Feng et al. in Science 312:1504–1508, 2006), sunscreens for ultraviolet absorbents (Imanaka et al. in Chem Mater 15:2289–2291, 2003), the adsorption and reaction of formaldehyde (Zhou and Mullins in Surf Sci 600:1540–1546, 2006), oxygen storage capacity, hybrid solar cells, H2S removal and luminescent materials for violet/blue fluorescence.
