Hierarchical hollow TiO2@CeO2 nanocube heterostructures for photocatalytic detoxification of cyanide†
Abstract
A facile generic strategy is employed to prepare hierarchical hollow TiO2@CeO2 nanocubes via fast simultaneously coordinating etching and precipitation reactions. The intrinsic hollow cubic nature, as well as the heterojunction effect of the unique nanostructures, contributes greatly to its enhanced performance for photocatalytic detoxification of cyanide.
