Abstract The development of active and durable photocatalysts without noble metals for green hydrogen generation is a major challenge in photocatalysis. Herein, composite nanomaterials based on TiO 2 coupled with HKUST‐1, copper metal–organic framework, by photocatalysis using water methanol as sacrificial agents are developed. To design highly composite, the mass ratios between HKUST‐1 studied optimized. photoactive materials characterized TEM, UV–vis spectroscopy, FTIR, XRD, XPS, photoelectrochemical studies. charge carrier dynamics also time‐resolved microwave conductivity crucial role investigated XPS electron paramagnetic resonance. DFT calculations used to understand mechanism involved H generation. findings reveal high evolution rate HKUST‐1/TiO (5.11 mmol g −1 h ) first cycle ratio (1:20). This activity increases cycling until surpassing performance 1 wt.% Pt (TiO material, benchmark known reference terms photocatalytic production, 13.24 obtained after sixth cycle.
