Nanoporous Distorted TiO2 Ribbons Combined with CdS for Photocatalytic Conversion of CO2 under Visible Light

Photoreduction of CO 2 into fuels via TiO 2 is conducive to mitigating the worsening global climate and the increasing energy crisis, while the low energy efficiency hinders its large-scale applications. In this work, nanoporous distorted TiO 2 ribbons combined with CdS are prepared to optimize the CO 2 photoreduction processes through the fast transmission of photoinduced charge carriers and the slow charge carriers' recombination in nanoporous distorted TiO 2 ribbons. The results showed that the formation rate of methanol in nanoporous distorted TiO 2 ribbons combined with CdS was 20.6 μmol g −1 h −1 , which was 1.82 times higher than that of TiO 2 nanoparticles combined with CdS.
