Rational design of catalysts towards energy-saving formaldehyde oxidation: A review

Abstract

Volatile organic compounds are the major concern with formaldehyde being the dominant indoor air pollutant. Exploring advanced catalysts towards energy-saving formaldehyde oxidation catalysts is the key to mitigate the risks from indoor air. This review summarizes the recent progress on enhancing oxidation of formaldehyde by tailoring the structure, morphology, surface, interface and external field of catalysts. The modification strategy of various catalysts is discussed with focus on mass transfer enhancement, surface manipulation, interface engineering and environment regulation. Future researches to address the remaining challenges on formaldehyde oxidation are also proposed, which are expected to inspire further sparkling ideas for development of energy-saving systems toward efficient removal of formaldehyde.
