摘要

The sol-gel entrapment of chromium (VI) within a silica matrix, obtained by oxidation with ozone of the corresponding entrapped chromium (III), was found to be an efficient and recyclable oxidizing system (at least up to 16 times) for benzylic alcohols. No leaching of chromium in solution was observed, which prevented any environmental pollution.
