SrNb2O6 nanoplates as efficient photocatalysts for the preferential reduction of CO2 in the presence of H2O.

We successfully synthesized SrNb2O6 with nanoplate morphology by a facile hydrothermal method. The SrNb2O6 nanoplate without any promoters or co-catalysts exhibited promising photocatalytic performance for the preferential reduction of CO2 with H2O vapour to CO and CH4 due to its high electron-hole separation and high CO2 chemisorption abilities.
