Abstract: Nickel oxide (NiO) thin film is metal oxide that has attracted much attention in recent years due to its environment friendliness. Like all metallic oxides semiconductors, thin films, NiO is gaining more and more attention as a promising photo-catalyst to replace powder catalysts, which are difficult in recycling. This paper summarized the photocatalytic activity of metallic oxides thin films. Furthermore, the results of several studies on the efficient photo-catalyst of NiO thin films and its components have also been shown. This review will be useful to researcher’s investigate non-toxic materials, with low production cost and high efficiency in the field of environmental protection.
