Abstract
Macroporous titania, which undergoes transition to the rutile phase by calc ination without collapse of the pore structure, is obtained by polymerizing a titania sol suspended around "colloidal crystals" of oil droplets. The d eformable template counteracts cracking of the titania phase. The Figure sh ows a scanning electron micrograph of a rutile sample with 200 nm pores obt ained by the method described.
