MoS2 Quantum Dots‐Modified Covalent Triazine‐Based Frameworks for Enhanced Photocatalytic Hydrogen Evolution

MoS2 quantum dots (QDs)-modified covalent triazine-based framework (MoS2 /CTF) composites are synthesized through an in situ photodeposition method. MoS2 QDs are well distributed and stabilized on the layers of CTFs by coordination of the frameworks to MoS2 . The QDs-sheet interactions between MoS2 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 MoS2 -modified g-C3 N4 (MoS2 /g-C3 N4 ) composite, making them promising materials for solar energy conversion.
