Hierarchically Mesostructured Titania Materials with an Unusual Interior Macroporous Structure

Outside mesoporous, inside macroporous. Mesoporous titania samples with an internal macroporous structure (see Figure) are reported to have been synthesized by a one‐step templating process. The materials have a thick shell and a sponge‐like macrostructured core with a uniform pore gradient. The syn...

Description
Summary:Outside mesoporous, inside macroporous. Mesoporous titania samples with an internal macroporous structure (see Figure) are reported to have been synthesized by a one‐step templating process. The materials have a thick shell and a sponge‐like macrostructured core with a uniform pore gradient. The synthesis conditions, particularly water content, are demonstrated to affect the pore structure crucially.
