MoS quantum dots (QDs)-modified covalent triazine-based framework (MoS /CTF) composites are synthesized through an in situ photodeposition method. MoS QDs are well distributed and stabilized on the layers of CTFs by coordination of the frameworks to MoS . The QDs-sheet interactions between MoS and CTFs facilitate interfacial charge transfer and separation. As a consequence, the composites exhibit outstanding photocatalytic activity and stability for hydrogen evolution under visible light irradiation (λ≥420 nm), that exceed those over pristine CTFs and MoS -modified g-C N (MoS /g-C N ) composite, making them promising materials for solar energy conversion.
通过原位光沉积法合成了二硫化钼量子点（QDs）修饰的共价三嗪基框架（MoS₂/CTF）复合材料。二硫化钼量子点通过框架与二硫化钼的配位作用而均匀分布并稳定在共价三嗪基框架层上。二硫化钼与共价三嗪基框架之间的量子点-片层相互作用促进了界面电荷转移与分离。因此，该复合材料在可见光照射（λ≥420 nm）下表现出优异的光催化产氢活性和稳定性，超过了原始共价三嗪基框架和二硫化钼修饰的石墨相氮化碳（MoS₂/g-C₃N₄）复合材料，使其成为太阳能转换的有前景的材料。
