Study on preparation of nano-TiO2 by W/O microemulsion reactor and its photocatalytic degradation of air pollution

Nanoscale and photocatalytically active TiO2 is widely used in many fields, such as environmental protection, pollution control, and the self-cleaning of textile and architecture. This paper (i) describes the preparation of nano-TiO2 in W/O microemulsion reactor, (ii) considers the photocatalytic degradation of air pollution caused by formaldehyde and toluene in terms of the bionics theory, and (iii) discusses the similarity between the photocatalytic degradation by nano-TiO2 and the photosynthesis of a plant that makes the degradation of pollutions by nano-TiO2 essentially important for ecologically safe treatment and recovery of natural resources.
