Abstract
The present invention relates to a nitrogen-doped carbon-wrapped nickel catalyst for synthesis of higher alcohols by assembly of bioethanol and a preparation method therefor. The preparation method includes the following steps: S1, subjecting a soluble nickel salt and polyacrylamide to stirring with water, completely dissolving and then drying to obtain a precursor, where a molar ratio of the soluble nickel salt to polyacrylamide is 1:(0.5-8); and S2, subjecting the precursor to pyrolysis in an inert atmosphere at 300° C.-800° C. for 1-6 hours to obtain the nitrogen-doped carbon-wrapped nickel catalyst. The catalyst prepared by the method of the present invention has an active phase with high dispersity which enables synthesis of higher alcohols by efficient assembly of small molecules, and has relatively high stability which can still maintain high conversion rate and high yield for organic phase after 10 times of repeated use.
