Amino‐regulated charge separation in MOF/CdS heterostructures for boosted photocatalytic hydrogen evolution
Abstract Effective charge separation is crucial for efficient photocatalytic hydrogen production in metal–organic frameworks (MOFs). Herein, CdS‐modified MOFs composites Y‐TPTC/CdS and Y‐TPTC‐NH 2 /CdS were synthesized with ordered porous structures and abundant active sites. Under visible light irradiation, Y‐TPTC/CdS and Y‐TPTC‐NH 2 /CdS exhibit optimal proportional hydrogen production rates of 1936 and 5650 µmol g −1 h −1 , respectively, representing 9.4 and 27.1 times higher than that of pure CdS (205 µmol g −1 h −1 ). The introduction of amino groups effectively suppressed recombination of photogenerated charge carriers, facilitating more efficient charge transfer and significantly boosting photocatalytic hydrogen production activity. This work provides important insights for developing advanced composite photocatalysts with improved charge separation kinetics for enhanced solar‐to‐hydrogen conversion efficiency.
