The rapid growth of economics and industry has caused significant damage to the environment and shortages of energy. The field of semiconductor photocatalysis is currently obtaining a significant deal of interest due to its great potential to aid in resolving issues such as energy scarcity and environmental pollution. One of the most creative strategies for achieving electron-hole pair separation is the construction of heterojunctions, which is accomplished by connecting two semiconductors in series. The methods of charge transfer are discussed in an overview of various heterostructures, including type-II and Z-scheme. Due to its narrow advantageous band edge being placed and band gap, Ag 3 PO 4 is the subject of intense research to induce the appropriate redox reactions. Despite its relevance, Ag 3 PO 4 has inherent limitations such as restricted visible light response and significant charge carrier recombination. This review discussing the performance of Ag 3 PO 4 /graphene oxide-based heterojunction against numerous organic contaminants under visible light illumination. The second part of this article reviews and discusses recent findings of the degradation of wastewater pollutants. These pollutants include organic dyes, antibiotics, and other compounds. This study offers a substantial addition to our understand of the process underlying heterojunction photocatalysis as well as the development of superior heterojunction composite photocatalyst.
