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

Photoreduction of CO2 into fuels via TiO2 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 TiO2 ribbons combined with CdS are prepared to optimize the CO2 photoreduction processes through the fast transmission of photoinduced charge carriers and the slow charge carriers' recombination in nanoporous distorted TiO2 ribbons. The results showed that the formation rate of methanol in nanoporous distorted TiO2 ribbons combined with CdS was 20.6 μmol g−1h−1, which was 1.82 times higher than that of TiO2 nanoparticles combined with CdS.
