Facet-dependent photocatalytic properties of AgBr nanocrystals.
Polyhedral AgBr nanocrystals, evolved from cubes through truncated cubes and finally to high-symmetry octahedra, which corresponds to a progressive shrinkage of exposed {100} facets and enlargement of exposed {111} facets, are prepared by facile precipitation reactions. The as- prepared AgBr nanocrystals exhibit facet-dependent catalytic properties, with the {111}-dominated octahedra showing the highest photocatalytic activities.
