摘要Mesoporous hollow silica spheres (MHSS) with uniform size were successfully prepared by introducing monodispersed polystyrene (PS) spheres as hard template and selected surfactant as soft template in acid condition. With assistance of different surfactants, a series of mesoporous shells were created and the used surfactants have a significant effect on the structural properties of MHSS. The highest surface area was 690.3 m(2) g(-1) on the MHSS which was achieved by using P123 as a soft template. The MHSS was further used for loading active Pt through the reaction between chloroplatinic acid or and sodium borohydride. The as -prepared Pt/MHSS catalyst exhibited high activity for VOCs' deep oxidation. (C) 2016 Elsevier B.V. All rights reserved.
