Description
Summary:The eco-friendly and efficient non-noble metal nanocatalysts have extensive applications in the effective conversion of biomass derivatives into high-value chemicals. Herein, a highly dispersed and stable layered NiCu/SiO.sub.2 catalyst was successfully prepared by a facile ammonia evaporation (AE) method, and then applied to the aqueous-phase furfural (FFR) selective hydrogenation to cyclopentanone (CPO). Under mild conditions, FFR is almost completely transformed. Moreover, compared with traditional preparation methods, the yield of CPO increases significantly to 95.4% by the AE method. This remarkable performance improvement can be attributed to the high dispersion of metal nanoparticles and the synergistic effect between Ni and Cu. Meanwhile, Cu can adjust the electronic structure of Ni, and change the adsorption configuration of FFR on Ni, thereby improving the yield of CPO. This work provides a facile strategy for designing efficient and stable non-noble metal nanocatalysts for the aqueous-phase FFR selective hydrogenation. Graphical
