Two-step hydrothermal synthesis of Sn2Nb2O7 nanocrystals with enhanced visible-light-driven H2 evolution activity

A two-step hydrothermal route is used to synthesize Sn2Nb2O7 nanocrystals with an average size of 20 nm. The as-obtained nanocrystals show enhanced visible-light-driven photocatalytic H2 production activity compared with bulk Sn2Nb2O7 powder.
