“…Various approaches were used to remove HCHO, such as adsorption, plasma technique, photocatalysis and thermal catalytic oxidation . The adsorption method is limited by the maximum adsorption capacity; plasma technique has problems of secondary pollution, high energy consumption, and high cost; photocatalysis is limited by the excitation light source .…”

Thermal catalytic oxidation is a promising and effective technique for the removal of harmful formaldehyde (HCHO) in indoor air. Manganese oxide is a mostly‐investigated non‐noble metal oxide catalyst and attracts much attention due to its better catalytic performance for formaldehyde oxidation at low temperature. In this review, the effect of manganese oxide crystal structure, surface morphology and microstructure, surface active oxygen species, reducibility as well as catalytic reaction conditions (temperature, relative humidity and HCHO initial concentration) on catalytic performance, and the catalytic mechanism over manganese oxide were summarized and discussed. The challenges and prospects for future development of manganese oxide in catalytic oxidation of formaldehyde are also covered.
