摘要：

Spherical hollow titania materials with a diameter of 60-100 nm and wall thickness of approximately 10 nm were synthesized using nanosized CaCO3 particles as inorganic templates. BET surface area of as-synthesized titania was 381.15 m(2)/g, and decreased to 124.36 m(2)/g after calcination at 500degreesC for 2 h.
