Nano-sized semiconductor powders for use as photocatalysts have great potential in environmental and energy engineering applications. The photocatalytic activity of photocatalyst is significantly affected by preparation process since the crystalline structure of photocatalyst is dependent on preparation conditions. This paper aims to give an overview of the research progress of nano-sized photocatalyst powder preparation technologies, including solid route, gas phase route, and liquid route. The advantages and disadvantages of different preparation technologies are analyzed and compared. The research direction and prospect of photocatalyst preparation method is analyzed.
