以分子氧为氧化剂，开发了新型钴基多相催化剂，用于醇的直接氧化酯化反应。热解的氮连接的乙酸钴（II）负载在商业碳转化为典型的均相配合物的高活性和选择性的非均相Co 3 O 4-N@C材料。通过在氧存在下应用这些催化剂，醇至酯的交叉和自酯化以良好至优异的产率进行。
Novel cobalt-based heterogeneous catalysts have been developed for the direct oxidative esterification of alcohols using molecular oxygen as benign oxidant. Pyrolysis of nitrogen-ligated cobalt(II) acetate supported on commercial carbon transforms typical homogeneous complexes to highly active and selective heterogeneous Co3O4-N@C materials. By applying these catalysts in the presence of oxygen, the cross and self-esterification of alcohols to esters proceeds in good to excellent yields.
