Porous Inorganic Materials from Living Porogens: Channel-like TiO₂ from Yeast-Assisted Sol–Gel Process

Vitality of yeast cells maintained in an aqueous sol-gel solution containing titanium tetraisopropoxide and glucose. The living cells and their metabolites acted as the porogens for a channel-like TiO2 precursor. Further processing of the precursor offered a channel-like meso/macroporous TiO2, a potential anode material for Li-ion battery.
