Macroporous and hollow titania materials have a wide range of applications
such as lightweight structural materials
catalytic supports
thermal and acoustic insulators
and photoelectric devices
because of their unique properties
like as high specific surface area
high damping capacity
low thermal conductivity
and low dielectric permittivity.This review summarizes research work of synthesizing structured titania materials including macroporous materials
and hollow capsules and tubes.Inverse opaline titania (photonic crystal) materials template synthesized using colloidal particle assembled templates are emphasized.Template synthesis of titania hollow spheres and nanotubes is also reviewed.
