摘要We have synthesized a series of LaPO4/g-C3N4core-shell nanowires via an in-situ hydrothermal growth of LaPO4nanorods in tubular g-C3N4and investigated their photocatalytic activity in CO2reduction. It was found that in the synthesized core-shell structure, the outer g-C3N4nano-shells coated on the LaPO4nanorod cores resulted in the enhanced light absorption and charge carrier separation/transfer ability, thus improved the room temperature photocatalytic performance of the nanocomposites in CO2photocatalytic reduction compared with the g-C3N4and LaPO4individuals. A maximum CO yield of 0.433 μmol has been obtained from CO2reduction within 1 h irradiation on 30 mg nanocomposite photocatalyst under the absence of any noble metal. Finally, a possible mechanism, which is featured with LaPO4activation due to significantly promoted separation/transfer of photo-generated charge carriers, was proposed. The encouraging performance in CO2photoreduction demonstrates that this novel nanocomposite will be a prospective material in environmental protection and energy conversion. © 2016
