Abstract

Cobalt-containing SiO2-based nanosphere with multi-nanochambers was prepared via a microemulsion method. Addition of cobalt ammonia complex to microemulsion is a necessary step to obtain this specific structure. This novel material was found to be an efficient catalyst for the decomposition of cyclohexyl hydroperoxide, and high activity of 94% conversion with 93% selectivity for K–A oil could be obtained.
