title: Different CdSeTe structure determined photoelectrocatalytic reduction performance for carbon dioxide.
abstract: CdSeTe nanoparticles (CdSeTe NPs)/TiO2nanotubes (TiO2NTs) and CdSeTe nanosheets (CdSeTe NSs)/TiO2NTs were fabricated by photoelectric deposition method and hydrothermal method, respectively. The band gap of the CdSeTe NPs/TiO2NTs (1.24eV) is narrower than that of the CdSeTe NSs/TiO2NTs (1.48eV). The photoelectrochemical conversion efficiency of the CdSeTe NPs/TiO2NTs is 2.72 times larger than that of the CdSeTe NSs/TiO2NTs, manifesting that the CdSeTe NPs/TiO2NTs possessed more excellent photocatalytic performance. Furthermore, the current density of electrocatalytic reduction CO2on the CdSeTe NPs/TiO2NTs was 2.47 times larger than that of the CdSeTe NSs/TiO2NTs, showing the excellent electrocatalytic performance of the CdSeTe NPs/TiO2NTs. The major product methanol was detected in the PEC reduction process on the two as-prepared materials. The yield reached 18.57mmolL-1after 300min on CdSeTe NPs/TiO2NTs, which is 16 times larger than that of CdSeTe NSs/TiO2NTs.
