Highly effective CoOx for catalytic transfer hydrogenation of plant oil to fatty alcohols

Abstract

Catalytic non-edible plant oil into high value-added fatty alcohols (FA-OHs) was highly demanded to substitute fossil utilization. Herein, we report a low-cost and highly effective self-supported CoOx catalysts for catalytic transfer hydrogenation (CTH) of plant oil to FA-OHs using isopropanol as hydrogen donor. The small size of selectively exposed crystal planes and homoatomic Co-CoO-Co3O4 interfaces explained for >80% high yield of alcohols observed on Co-DP catalyst at 200 °C in 5 h. The plausible reaction pathway of CTH plant oil based on the detailed investigation of reaction conditions was proposed.
