MoS Quantum Dots-Modified Covalent Triazine-Based Frameworks for Enhanced Photocatalytic Hydrogen Evolution.

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.
