Strontium niobates (SrNb2O6 and Sr2Nb2O7) with regular nanostructures were synthesized by a facile flux method. Ag-loaded SrNb2O6 and Sr2Nb2O7 exhibited different performances for the photocatalytic reduction of CO2 in H2O. Compared to Sr2Nb2O7 nanoflakes and Sr2Nb2O6 nanoparticles, SrNb2O6 nanorods exhibited higher photocatalytic activity and selectivity toward CO evolution. Stoichiometric amounts of CO (51.2 mu mol h(-1)) and H-2 (1.1 mu mol h(-1)) as the reduction products, in addition to O-2 (24.8 mu mol h(-1)) as the oxidation product, were obtained, indicating that H2O serves as an electron donor in the photocatalytic conversion of CO2. In addition, the effect of the Ag cocatalyst on the photocatalytic conversion of CO2 was investigated. (C) 2017 Elsevier B.V. All rights reserved.
