摘要
Mesoporous SiO2@TiO2 core/shell nanospheres with a specific surface area of 567-673 m2 g-1 and an average pore size of 1.5-2.8 nm are successfully prepared using a facile method combining sol-gel and thermal treatment processes. The nanospheres exhibit excellent adsorption capability and photodegradation toward rhodamine B (RhB) in pollutant solution. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
