Enhanced Photothermal Selective Conversion of CO2 to CH4 in Water Vapor over Rod-Like Cu and N Co-Doped TiO2
文献摘要：
Enhancing catalytic efficiency and selectivity is critical issues for CO2 conver-sion.The rod-like Cu/N co-doped TiO2 samples(Cu/N-TiO2)were synthesized by the elec-trospinning-calcination method.The substitutional Cu and interstitial N doping not only en-hanced visible-light absorption ability,but also formed the Ti(Ⅲ)sites.The obviously syner-gistic effect between the photocatalysis and thermalcatalysis appeared for CO2 conversion over the 8-Cu/N-TiO2 catalyst.After 9 h visible-light-illumination at 160℃,the CO,CH4 and O2 yields reached 49.7,1455.1 and 2910.2 μmol/gcat,respectively.In the 7th cycling,the yields of two main CH4 and O2 products were slightly down by less than 11.5％,and the selectivity of CH4 product kept above 98％.Combined with the theoretical surface mode,Cu/N co-doping could promote the adsorption-ability for H2O and CO2 molecules and reduce activation-energy for CO2 conversion.Hence,the co-doping construction showed a great significance of designing efficient photothermal catalysts for the CO2 conversion application.
