Transition Metal Dichalcogenide Hybrids for Visible-light-driven Photocatalytic Dye Degradation

The 21st century has seen tremendous industrialization in many countries worldwide, making environmental protection and energy conversion important issues. As such, investigations on the decomposition of dye molecules in water for environmental protection and clean energy construction are challenging yet impressive. It is still difficult to create a photocatalyst with a sensible design that is affordable and extremely effective for degrading organic dye contaminants. Our work showcases an incredibly effective “interfacial connection and suitable band gap matching” method to create nano-architecture hybrid catalysts based on Transition metal dichalcogenides (TMDs) built using hydrothermal processes. With its large surface area, colossal energetic sites, and interfacial charge assignment, the TMDs-based nano-hybrid catalyst significantly enhances the catalytic degradation of dye pollutants. This demonstration could provide a new hybrid catalyst that degrades dye molecules more effectively and sustainably when exposed to visible light. Lastly, certain recommendations are emphasized for advancing hybrid catalysts based on transition metal dichalcogenides in the future.
