MoS/ZnInS flower-like heterostructures into porous carbon (PC@MoS/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 study focuses on enhancing the photocatalytic performance of zinc indium sulfide (ZIS) by creating a ternary heterojunction with molybdenum disulfide (MoS) and graphene quantum dots (GQDs).
- This new structure improves light absorption and utilizes specialized interfaces to increase the efficiency of electron transfer and reduce carrier recombination.
- The results show a significant increase in hydrogen production rates, making the MoS/ZIS/GQDs heterojunction 36.7 times more effective than pure ZIS, indicating its potential for better solar energy conversion applications.
Iridium oxides (iridates) provide a good platform to study the delicate interplay between spin-orbit coupling (SOC) interactions, electron correlation effects, Hund's coupling and lattice degrees of freedom. An overwhelming number of investigations primarily focus on tetravalent (Ir, 5d) and pentavalent (Ir, 5d) iridates, and far less attention has been paid to iridates with other valence states. Here, we pay our attention to a less-explored trivalent (Ir, 5d) iridate, KNaIrO, crystallizing in a triangular lattice with edge-sharing IrO octahedra and alkali metal ion intercalated [IrO] layers, offering a good platform to explore the interplay between different degrees of freedom.
