| 英文摘要 | Development of new visible-light-responsive materials is highly desirable in photocatalysis. here, a novel oxide material licuta3o9 (lcto) with a characteristic perovskite-like structure, exhibiting a visible light absorption edge of approximate to 500 nm due to the hybridization of cu 3d and o 2p orbitals, is reported. the structure of the as-obtained lcto is experimentally characterized and theoretically simulated. uv-vis diffuse reflectance spectroscopy, mott-schottky, and density functional theory calculation results show that the lcto is an n-type semiconductor with bandgap of approximate to 2.48 ev and exhibits suitable conduction band and valence band positions of approximate to-0.45 and 2.03 ev vs reversible hydrogen electrode, respectively. based on initial optimization of preparative conditions and loading of cocatalysts, the as-modified lcto sample can drive both water reduction and oxidation half reactions in the presence of corresponding sacrificial reagents under visible light irradiation (lambda >= 420 nm), demonstrating its promising application in solar water splitting. the dual functional features of lcto render it a promising photocatalyst for one-step overall water splitting to produce hydrogen. in addition, the unobvious structural change of the lcto photocatalyst during the reaction and repeated runs of the photocatalytic h-2 evolution reaction demonstrate its good photochemical stability. |
