Exploring Photocatalytic and Photoelectrochemical Applications of g-C3N4/Metal Sulfide Quantum Dots Nanocomposites: A Review of Recent Trends and Innovations

초록

Global environmental contamination will worsen, requiring innovative solutions based on cutting-edge research. Photocatalysis has advanced in recent years by using metal sulfide quantum dots (QDs), graphitic carbon nitride (g-CN), and their nanocomposite heterojunctions. This systematic study examined the latest developments in this revolutionary area. The article begins by describing metal sulfide QDs and the optical, electrical, and structural characteristics of metal sulfide QDs and g-CN. Appreciating the tremendous potential of these materials to solve environmental issues begins with these realizations. The major attraction, nanocomposite heterojunctions, was next examined. We examine the fascinating world of g-CN-metal sulfide QD composites, including their synthesis, cooperative behavior, and heterojunction topologies such as Type I, Type II, Zscheme, and S-scheme. These heterojunctions unlock the photocatalytic efficiency hitherto unreachable. We learn how these heterostructures boost photocatalytic efficiency, revealing their revolutionary potential. This review shows how these advances are used in real life. These materials have accelerated the shift toward a cleaner, sustainable future by degrading organic contaminants and converting CO(2 )into useful compounds.
