Thickness-Dependent Photocatalysis of Ultra-Thin MoS<sub>2</sub> Film for Visible-Light-Driven CO<sub>2</sub> Reduction
The thickness of transition metal dichalcogenides (TMDs) plays a key role in enhancing their photocatalytic CO<sub>2</sub> reduction activity. However, the optimum thickness of the layered TMDs that is required to achieve sufficient light absorption and excellent crystallinity has still...
