A composite surfactant route for the synthesis of thermally stable and hierarchically porous zirconia with a nanocrystallized framework

A thermally stable, hierarchically porous zirconia material is synthesized using a composite template of block copolymer and surfactant. The zirconia has a high surface area, a nanocrystallized framework, a well-defined one-dimensional macroporous structure, and a very uniform mesopore distribution (see Figure).
