Multi anion-based materials: Synthesis and catalytic applications

Rapid growing energy demands owing to the reduction of fossil fuels as well as environmental pollution call for renewable, environment-friendly energy sources. Photocatalysis has widely applied for water splitting to generate H-2, oxygen evolution, organic synthesis, pollutants degradation, and much more. Today, various multi anion materials are used, which are synthesized via easy and environment-friendly methods. The multi-anion materials mainly consist of N/C/O, S/O, N/F/O, and N/O, which shows excellent photocatalytic activity. Also, multi-anion contains metal cations and two anionic species. Multi-anion photocatalysts have vast absorption bands and visible-light absorption efficiency. This review discusses the basic information of multi-anion compounds like synthesis, physical and chemical properties. Meanwhile, some research progress of multi anion materials was also given for CO2 reduction, water splitting, and pollutants removal.
