Abstract
MoS(2)/ZnIn(2)S(4) flower-like heterostructures into porous carbon (PC@MoS(2)/ZIS) are embedded. This ternary heterostructure demonstrates enhanced light absorption across a broad spectral range from 200 to 2500 nm. It features both Type-II and S-scheme dual heterojunction interfaces, which facilitate the generation, separation, and transfer of photoinduced carriers. The PC enveloped by MoS(2)/ZIS composite microspheres serves as a photothermal source, providing additional energy to the carriers. This process accelerates charge separation and migration, enhancing photothermal-assisted photocatalytic H(2) evolution. The optimal H(2) evolution rate for PC@MoS(2)/ZIS reaches an impressive 18.79 mmol g(-1) h(-1), with an apparent quantum efficiency of 14.1% at 400 nm. This work presents a promising approach for effectively integrating multicomponent heterostructures with photothermal effects, offering innovative strategies for efficient solar energy utilization and conversion.
