Co-Ag supported ZnO: An efficient and recyclable heterogeneous catalyst for the oxidation of natural terpenes

Co-Agco-doped ZnO has been used as a sheep and environmentally catalyst in the oxidation of natural terpenes. The reaction was achieved in the presence of hydrogen peroxide as clean oxidizing agent under mild conditions. We have shown that the catalyst is very active toward mono and sesquiterpenes with the formation of ketones as major product with 50% of yield. (C) 2019 Elsevier Ltd. All rights reserved.
