摘要：
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 (lambda >= 420 nm), that exceed those over pristine CTFs and MoS2-modified g-C3N4 (MoS2/g-C3N4) composite, making them promising materials for solar energy conversion.
