Ru Nanoparticles Supported on Mesoporous Al‐SBA‐15 Catalysts for Highly Selective Hydrogenation of Furfural to Furfuryl Alcohol

Abstract

Furfuryl alcohol, which is the hydrogenated product of furfural, has been identified as a very promising platform chemical with high potential for applications in the manufacture of key chemicals, lubricants, fragrances, and pharmaceuticals. In this work, bare SB, and x % Ru/Al‐SB (x=1.5, 2.5, 3.5, and 4.5 wt. %) samples were fabricated by a hydrothermal method. Bare and most active catalysts were characterized by different techniques, such as BET, FE‐SEM, TEM, FT‐IR, and XRD, to understand their physical and chemical properties. An evaluation of the effects of various reaction parameters, such as catalyst loading, reaction temperature, and reaction time, on the catalytic performance, showed higher catalytic conversion of furfural and selectivity for the desired products. The most active RuS3 catalyst showed 100 % conversion of furfural and 99 % selectivity for furfuryl alcohol. It could be reused for five consecutive reaction cycles without significant loss of performance. In addition, Ru leaching and loss of conversion or selectivity were not noticed during the five‐run recycling test. The EDS elemental mapping analysis of the used catalyst established the preservation of the mesoporous structure, suggesting a strong interaction between the hexagonal porous silicate and the Ru nanoparticles.

Progress in Cobalt Complexes for Enabling Asymmetric Hydrogenation, H2 Production Catalysis and Alkene/Alkyne Hydro‐functionalization: A Review

“…[33,34] Over the course of last ten years, extensive focus has been on research based upon exploring numerous low-cost metal complexes as potential catalysts for the H 2 evolution process (HER). Several notable examples of successful synthetic HER catalysts include cobalt-diamine dioxime, [35][36][37][38][39][40] cobalt polypyridyl, [41][42][43][44] cobalt corrole-porphyrins, [45,46] cobalt nanoparticles, [47] bimetallic complexes, [48,49] dithiolate complexes, [50] carbene complexes, [51] cyclopentadienyl complexes, [52] macrocyclic complexes, [53] rhodium complexes, [54] ruthenium polypyridine complexes [55][56][57][58] and nanoparticles, [59] cobalt complexes [60] and particularly notable examples are found in nickel compounds containing diphosphine ligands with nitrogen bases, [61] which have shown high effectiveness as synthetic HER catalysts. Many compounds based on di-iron were created to simulate the [Fe 2 ] sub-site of the [FeFe]hydrogenase enzyme.…”
