Synthesis and Applications of Nanomaterials With High Photocatalytic Activity on Air Purification

Nanomaterial-based photocatalysis, a promising strategy for the purification of atmospheric air pollutants, has attracted more and more attention in recent years. The removal efficiency of air pollutants greatly depends on the phase structure, morphology, and surface texture of the nanophotocatalysts. Recently, constructing nanophotocatalysts with porous structure and specific chemisorption toward target pollutants is highly emphasized, because it allows the low-concentration reactants to readily accumulate onto/around the surface of nanophotocatalysts, which can improve the photocatalytic activity. In this chapter, the synthesis, characterization, and properties of bismuth compounds, perovskite oxides, and g-C3N4-based nanophotocatalysts are investigated, aiming to elucidate the relationship between the microstructures and properties of nanophotocatalysts. The contents of this chapter can give implications to researchers in the field of air pollution control and environmental catalysis.
