The component for photocatalyst is a developing field in energy production. Various photocatalysts can be synthesized using a variety of techniques. Numerous researchers have identified a wide range of photocatalysts. While ternary-based composite photocatalysts have received relatively little attention, plenty of reviews are available on photocatalysts. We provide a short summary of the most recent and a variety of ternary-based composite photocatalysts here. We discuss gold (Au)-based, silver (Ag) based, zinc oxide (ZnO) based, and other ternary-based composites in this paper. This quick summary will help future demonstrations of increased deterioration efficiency. This will provide insight for future research on ternary-based composite photocatalysts.
