Enhanced photoreduction CO2 efficiency by criss-crossed TiO2 nanoflakes combined with CdS under visible light

In this paper, a novel photocatalyst CNCC with excellent visible light photocatalytic performance was successfully prepared to optimize the CO2 photoreduction performance. The results showed that the methanol formation rate of CNCC was 24.7 µmol g−1 h−1, which was 1.42 times higher than that of NCC. The enhanced photoactivity is attributed to the rapid propagation of charge carriers induced by light from the constructed composite structure.
