【 摘 要 】

tsBiVO4 nanowires with exposed (010) facets were deposited on the piezoelectric transducer piezo-substrate.CO2 conversion rate was significantly improved by 5.5-time in an electrostatic field generated by applying a stress on the piezo-substrate.The mole percentage of methane in products was increased from 29% to 64%.The improved performance was attributed to the facilitated photo-carriers separation/transfer, as well as the enhanced adsorption of polar molecules.
