MoS 2 quantum dots (QDs)‐modified covalent triazine‐based framework (MoS 2 /CTF) composites are synthesized through an in situ photodeposition method. MoS 2 QDs are well distributed and stabilized on the layers of CTFs by coordination of the frameworks to MoS 2 . The QDs–sheet interactions between MoS 2 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 2 ‐modified g ‐C 3 N 4 (MoS 2 / g ‐C 3 N 4 ) composite, making them promising materials for solar energy conversion.
