Ruthenium Nanoparticles Intercalated in Montmorillonite (nano-Ru@MMT) Is Highly Efficient Catalyst for the Selective Hydrogenation of 2-Furaldehyde in Benign Aqueous Medium

Abstract

Chemoselective hydrogenation of 2-furaldehyde to furfuryl alcohol using green solvents is an important research area to get eco-friendly fuels and fine chemicals. Herein, we report ruthenium nanoparticles (~1.8 nm) intercalated in montmorillonite as an efficient catalytic system, which can selectively hydrogenate 2-furaldehyde in a benign aqueous medium. The complete conversion was observed at 40 °C with 1 MPa H2, the selectivity of furfuryl alcohol being >99%, and turnover number 1165. After a catalytic run, the montmorillonite-supported ruthenium nanoparticles can be recycled and reused without losing their activity and selectivity.

Porous Hollow Nanostructure Promoting the Catalytic Performance and Stability of Ni3P in Furfural Hydrogenation

“…Noble metal catalysts could hydrogenate the aldehyde group under mild conditions, so they were used as selective hydrogenation catalysts for FF, such as Au, 15 Ag, 16 Pd, 17 Pt, 18 and Ru. 19 However, high cost was still an economic barrier to the widespread application of precious metal catalysts. To reduce the production cost, a variety of non-noble metal catalysts were exploited, such as CuHAp, 20 Cu/Cu 2 O, 21 Cu/ZrO 2 , 22 Cu/SBA-15, 23 ZnCo-US@NC, 24 Co-N-C, 25 Co/Zn@NPC, 26 Ni, 27 and LaFeO 3 .…”

“…Until now, many catalyst systems have been developed for FF hydrogenation to form FOL. Noble metal catalysts could hydrogenate the aldehyde group under mild conditions, so they were used as selective hydrogenation catalysts for FF, such as Au, Ag, Pd, Pt, and Ru . However, high cost was still an economic barrier to the widespread application of precious metal catalysts.…”
