Rational design for the fabrication of bulk NiSn alloy catalysts for the synthesis of 1,4-pentanediol from biomass-derived furfural without acidic co-catalysts.

This study describes the rational design for the fabrication of bulk NiSn alloy catalysts for the de/hydration-hydrogenation of biomass-derived furfural (FFald) to 1,4-pentanediol (1,4-PeD) without the acidic co-catalyst. The presence of both hydration active sites (Brønsted acid sites (Ni-SnO)) and hydrogenation active sites (Ni or Ni-Sn alloy) in NiSn alloy could be controlled by changing the pH of Ni-Sn solution during the preparation. Both active sites acted synergistically to catalyse the de/hydration-hydrogenation reactions of FFald to produce a high yield of 1,4-PeD in a batch reaction system at 433 K, 3.

Unravelling the one-pot conversion of biomass-derived furfural and levulinic acid to 1,4-pentanediol catalysed by supported RANEY® Ni-Sn alloy catalysts.

Bimetallic Ni-Sn alloys have been recognised as promising catalysts for the transformation of furanic compounds and their derivatives into valuable chemicals. Herein, we report the utilisation of a supported bimetallic RANEY® nickel-tin alloy supported on aluminium hydroxide (RNi-Sn()/AlOH; is Ni/Sn molar ratio) catalysts for the one-pot conversion of biomass-derived furfural and levulinic acid to 1,4-pentanediol (1,4-PeD). The as prepared RNi-Sn(1.

Preparation of a Highly Stable Pd-Perovskite Catalyst for Suzuki Couplings via a Low-Temperature Hydrothermal Treatment.

Pd-perovskite (Pd-STO, STO = SrTiO) was synthesized by a relatively low-temperature (373 K) hydrothermal method without calcination. The morphology of the Pd-STO could be controlled by adjusting the HO/NH ratio during the fabrication of the amorphous titania. The Pd-STO catalyst showed better durability for Suzuki couplings than did Pd-impregnated catalysts on conventional supports.
