A Comparison Study of Different Photocatalyst Preparation Methods: A Review on RGO-BI2MoO6 Photocatalyts Synthesis Methods

Abstract

The use of photo catalysts for the degradation of organic pollutants in water is widely growing and the application of photodegradation process has been seen to be effective in most organic pollutants. Different photocatalysts have been studied and various methods for photocatalysts preparations have been developed and investigated. Different methods have been experimented by different researchers in order to see how they improve the physicochemical properties of the photocatalysts since they have an influence on the on their performance. This paper will review different methods for the synthesis of commonly used photocatalysts while focusing more on the RGO-Bi 2 MoO 6 as it is one of the new photocatalysts attracting a lot of attention in research. Comparison of different methods will be done to see how each methods affect the final structure of the materials. Moreover, advantages and disadvantages of each method will be compared. The methods to be reviewed will be classified into physical and chemical synthesis methods. Finally, this study will identify the best method to use when developing RGO-Bi 2 MoO 6 for degradation purposes.Keywords-Chemical methods, photocatalysts, physical methods, RGO-Bi 2 MoO 6 , synthesis. I. INTRODUCTIONPhotocatalysis has been widely applied in the photodegradation of most pollutants such as dyes, polycyclic aromatic hydrocarbons and other chemicals that are not easily degradable. Various photocatalysts have been employed to degrade contaminants occupying the environment (e.g pesticides and PAHs). Owing to the fact that, the application of photocatalysis in degradation of pollutants has been found to be effective [1]. Photocatalytic degradation of pollutants has been widely studied and different photocatalysts have been explored Manuscript
