Development of the removal of indoor formaldehyde with catalytic oxidation

The latest development in the treatment of indoor formaldehyde pollution with oxidation technique is summarized. Firstly, catalytic oxidation is proposed to remove formaldehyde on the basis of the shortcomings in the existing methods commonly used in the removal of formaldehyde. Then the principle and effect of the present photocatalytic apparatus and the modification of photocatalysts are introduced. In addition, the research on the removal of indoor formaldehyde with heterogeneous catalytic oxidation is presented in detail. Finally, some methods combining catalytic oxidation and other methods in the removal of indoor formaldehyde are introduced as well. After the analysis of indoor formaldehyde removal, and from the view point of efficiency and energy consumption, it is concluded that low temperature catalytic oxidation is one of the available and most effective techniques in the removal of indoor formaldehyde.
