TiO2 monoliths were prepared, characterized, and evaluated for photocatalytic performance. The TiO2 monoliths were found to have an interconnected void lattice and a bimodal porous structure with macropores and mesopores after calcination at 500-700 degrees C. Monoliths calcined at 500 degrees C had high specific surface area (93.1 m(2)/g) and porosity (68%), which were maintained after calcination at 700-1100 degrees C (51-46%). The calcined monoliths had relatively high Vickers hardness (similar to 104) despite their porous structure. Monoliths calcined at 500 and 700 degrees C exhibited high performance because of their high specific surface area.
