摘要：
The low-concentration HCHO removal at room temperature is still a challenge in the indoor air purifying. Manganese dioxide catalyst (MnO2-M) derived from metal-organic frameworks (MOF) was synthesized via facile in-situ redox reaction. The obtained MnO2-M catalyst displayed superior activity and stability for low-concentration HCHO removal, reaching similar to 95% for 1.0 mg/m(3) of HCHO under dynamic test mode and degrading 93.1% for 1.0 mg/m(3) HCHO in 3 h under static test mode at room temperature. Moreover, the enhanced activity of MnO2-M could be attributed to the abundant chemisorbed oxygen species, numerous Mn-vacancies and proper pore size distribution. More crucially, the chemisorbed oxygen species on the MnO2-M could be rapidly activated by the transferable electrons and vacancies, thus significantly promoting the formation of reactive oxygen species and HCHO decomposition. The present work provides a new strategy to develop efficient catalyst for indoor air purification.
