Synthesis of highly ordered mesoporous tantalum oxide

The pore arrangement of mesoporous tantalum oxide prepared with a block copolymer surfactant as a structure-directing agent is remarkably improved by optimizing the amounts of metal source and water content. In contrast to the wormhole-like pore structure observed in the mesoporous tantalum oxide prepared under standard conditions, a highly ordered mesoporous structure is formed under optimized conditions.
