Water pretreatment promoting the removal of indoor formaldehyde over nano-CeO₂ at ambient temperature

Abstract

An efficient and noble-metal-free catalyst is of practicality for ambient temperature removal of indoor formaldehyde (HCHO) which severely haunts human’s health. In this work, a commonly used nano-CeO2 material is...

Recent advancements in CeO2-enabled liquid acid/base catalysis

“…Ceria (CeO 2 ) with distinctive properties has been extensively employed as a catalyst or catalytic support for various heterogeneous reactions. 14–21 The most well-established applications of CeO 2 -based materials is embodied in the construction of three-way catalysts (TWCs) in automobiles, where CeO 2 works as an oxygen storage material, improving the performance of TWCs for the oxidation of CO and unburnt hydrocarbons as well as the reduction of nitrogen oxides (NO x ). 14,22–26 Similar to the application of TWCs, the broad utilization of CeO 2 in heterogeneous catalysis primarily originated from its unique reversible Ce 3+ /Ce 4+ redox pair.…”
