In the current anthropocene, environmental pollution is a global problem that is inextricably linked with rapid industrialization and urbanization. Pollution hampers the environment sustainability and ecosystem services. Realizing the importance of keeping our planet clean, researchers are actively working for eco- friendly alternative technologies for all areas of daily life. With the environmental safety becoming the research focus, water environmental security, as an updating research direction has also been the concern. Nano- titania photo catalysis can prevent environmental pollution from the sources and ensure the fundamental productions in the industry. The main aim of this review paper is to give an overview of the enhanced photo catalytic activities of titanium dioxide (TiO2) nanoparticles. This review includes the basic properties of photo catalyst and mechanism of photo catalysis process followed by unique photo catalytic properties and research of TiO2 nano particles as photo catalysts. An effort has also been made to give an overview of expedient photo catalytic activity of these doped nano particles. The applications of nano particle photo catalytic technology in environmental safety are reviewed. Emphasis is put on the applications of nano- titania photo catalytic technology in wastewater treatment, and the latest achievements in scientific research of nano particle photo catalytic technology in wastewater treatment are given.
