As a new generation of environmental friendly catalyst, nanocatalyst has a great potentially application in air pollution control, especially in indoor air purification. In this paper, several typical nanocatalytic techniques, including photocatalytic air purification, vehicle exhaust controlling, fossil fuel desulphurization and reducing greenhouse effect are reviewed. Finally, the key scientific problems which need to be further solved are analyzed and forecasted.
