Inverse opal TiO2 as visible-light driven photocatalysts

Semiconductor photocatalysts have attracted a great deal of attention due to their potential application in environmental remediation. Titanium dioxide has been extensively investigated as the most promising photocatalyst. To improve the optical response of TiO2 in the visible region, Inverse Opal TiO2 has been recognized as an efficient photocatalyst due to its unique properties in terms of uniformly ordered and interconnected macroporous architecture.
