Mesoporous hollow silica nanospheres (MHSNS) with an average diameter of 100 nm and wall thickness of approximately l0 nm were synthesized via core-shell structure of CaCO3@SiO2 by a one-pot route.Hollow silica nanospheres with mesoporous shell were obtained by dissolving CaCO3 in HCl dilute solution.The characterization of as-prepared hollow products by BET indicates that MHSNS have a specific surface area of 865 m2/g and a narrow pore size of 3.78 nm.
