摘      要：Photocatalytic CO_(2)reduction reaction(CORR)is an environment-friendly technique for clean fuel *** low-cost and efficient photocatalyst/cocatalyst systems for boosting CORR is still a ***,a novel Bi_(2)O_(2)SiO_(3)/Ti_(3)C_(2)2D/2D heterojunction photocatalysts are successfully prepared by in situ growth of BiOSiOon the surface of ultrathin TiCnanosheets,a kind of *** observed Bi_(2)O_(2)SiO_(3)/Ti_(3)C_(2)(BOSO/TC-2)hybrids exhibit a large interface contact area companied with enhanced CO_(2)adsorption capability,illustrating excellent 2D/2D interfacial charge transfer *** total yield of products obtained on the optimized Bi_(2)O_(2)SiO_(3)/TC-2 photocatalyst is 3.8 times that of pristine BiOSiOnanosheets and achieve near 90%selectivity for CO over CHOH without sacrificial agents,which was higher than most all inorganic Bi-based ***,the mechanism of enhanced photocatalytic activity and reaction pathway was proposed in terms of the DFT study and in situ FTIR *** work might provide new semiconductor/cocatalyst systems for selective CO_(2)photoreduction to solar fuels.
