Abstract:
CdSeTe nanoparticles (CdSeTe NPs)/TiO2 nanotubes (TiO2 NTs) and CdSeTe nanosheets (CdSeTe NSs)/TiO2 NTs were fabricated by photoelectric deposition method and hydrothermal method, respectively. The band gap of the CdSeTe NPs/TiO2 NTs (1.24eV) is narrower than that of the CdSeTe NSs/TiO2NTs (1.48eV). The photoelectrochemical conversion efficiency of the CdSeTe NPs/TiO2 NTs is 2.72 times larger than that of the CdSeTe NSs/TiO2 NTs, manifesting that the CdSeTe NPs/TiO2 NTs possessed more excellent photocatalytic performance. Furthermore, the current density of electrocatalytic reduction CO2 on the CdSeTe NPs/TiO2 NTs was 2.47 times larger than that of the CdSeTe NSs/TiO2 NTs, showing the excellent electrocatalytic performance of the CdSeTe NPs/TiO2 NTs. The major product methanol was detected in the PEC reduction process on the two as-prepared materials. The yield reached 18.57mmolL-1 after 300min on CdSeTe NPs/TiO2NTs, which is 16 times larger than that of CdSeTe NSs/TiO2 NTs.
