The photocatalytic hydrolysis method represents a significant potential solution to the dual challenges of energy security and environmental sustainability. selection suitable materials systems is paramount importance for successful implementation hydrogen production technology. In this study, in situ reduction Co nanoparticles on MnO was successfully performed by calcining MnCo-PBA. Furthermore, graphdiyne (GDY) introduced physical agitation. introduction GDY reduced Co/MnO agglomeration made Co/MnO/GDY catalyst exhibit high activity production, with an optimum rate 2117.33 μmol·g-1·h-1, which 4.88 2.67 times higher than that Co/MnO, respectively. results photoelectrochemical test indicate composite has better photogenerated carrier separation efficiency. X-ray photoelectron spectroscopy, density functional theory calculations, electron paramagnetic resonance were used investigate transfer mechanism during process, confirming presence S-scheme heterojunction ohmic junction, enhance carriers. GDY-based constructed study significantly bimetallic catalysts.
