Опубликована: Апрель 14, 2025

Cocatalyst engineering is critical for advancing photocatalysis, as it suppresses charge carrier recombination, promotes interfacial electron/hole extraction, and serves active sites redox reactions. However, the incompatibility existing between cocatalyst host photocatalyst, along with its intrinsic properties of sites, limits further improvements in separation, surface reaction kinetics, overall performance. Herein, we introduce palladium hydrides (PdHx) an efficient on SrTiO3 (STO) photocatalytic water splitting, owing to their similar lattice parameters. The constructed PdHx/STO demonstrates a remarkable 6.4-fold enhancement hydrogen evolution compared Pd/STO control, reaching rate 5 mmol·g-1·h-1 at stoichiometric H2/O2 ratio 2:1. Structural characterizations theoretical analyses prove that situ formed PdHx feature advantages accelerated electron extraction modulated adsorption energies evolution; femtosecond transient absorption spectroscopy reveals prolonged lifetime improved transfer efficiency.

The urgent need for sustainable CO2 conversion technologies has driven the development of advanced photocatalysts that harness solar energy. This study employs a CTAB-assisted solvothermal method to fabricate Z-scheme heterojunction Fe-MOFs/VO-Bi2WO6 (FM/VO-BWO) photocatalytic reduction. Positron annihilation lifetime spectroscopy (PALS) was employed confirm existence oxygen vacancies, while spherical aberration-corrected transmission electron microscope (STEM) characterization verified successful construction heterointerfaces. X-ray absorption fine structure (XAFS) spectra confirmed defect configuration and heterostructure changed surface chemical valence state. optimized 1.0FM/VO-BWO composite demonstrated exceptional performance, achieving CO CH4 yields 60.48 4.3 μmol/g, respectively, under visible-light 11.8- 1.5-fold enhancements over pristine Bi2WO6. enhanced performance is attributed vacancy-induced active sites facilitating CO₂ adsorption/activation. In situ molecular formation critical CO2-derived intermediates (COOH* CHO*) through interactions involving four-coordinated two-coordinated hydrogen-bonded water molecules. Furthermore, accelerated interfacial charge transfer efficiency mediated by been conclusively demonstrated. work establishes paradigm defect-mediated design, offering route fuel production.
