Removal of Indoor Formaldehyde with Nanoscale Catalytic Oxidation

Abstract:

Catalytic oxidization has been studied for elimination of indoor formaldehyde. It was found that manganese dioxide (MnO₂) is the most effective catalyst among all the tested catalysts at room condition. In the present investigation, the formaldehyde removal efficiency of several commercially available MnO₂ catalysts was studied with typical method. Studies showed that the efficiency of MnO₂ can be affected by the particle size, the dispersity and the work hours.
