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.
