Surfactant-assisted synthesis of unprecedented hierarchical meso-macrostructured zirconia

A surfactant-assisted one-step synthesis route was developed, leading to the formation of a very high surface area (600 m 2 g -1) of zirconia and unprecedented hierarchical meso-macroporous structure with wormhole-like mesoporous walls and a novel, uniform assembly of macropores ranging in size from 300 to 500 nm
