Nanomaterial-based photocatalysis, a promising strategy for atmospheric air purification, has attracted increasingly more attention in recent years. Scientists are anticipating a new breach to prepare functional nanomaterials in large-scale for eliminating gas pollutants such as NO_x, VOCs and HCHO with high efficiency. Moreover, the development and fabrication of air purification units and devices based on photocatalysis technology are highly emphasized. These efforts can contribute to the sustainable development of the wholeindustry. In this study, the new challenges and prospects for nanomaterial-based photocatalysis technology are discussed in detail.
