AI Technical Summary
In existing methods for preparing catalysts for the hydrogenation of esters to produce lower alcohols, uneven nucleation of metal particles leads to easy agglomeration and carbon deposition of active catalyst particles, affecting the service life and activity of the catalyst.
In-situ growth of active metal Cu nanoparticles was achieved using native wood via a hydrothermal method. The hydrophilic groups on the surface of the pores and the vascular structure of the biochar material enabled the orderly distribution of the co-catalyst metal sites, forming an alloy and improving the dispersibility and stability of Cu species.
Under mild conditions, the catalytic activity and stability of ester hydrogenation to produce lower alcohols were improved, the catalyst lifespan was extended, and high conversion and selectivity were observed in the hydrogenation of methyl acetate to ethanol.
