Abstract

A simple way to nickel based mesoporous carbons: Inexpensive nanocatalysts for the hydrogenolysis of sorbitol

Highlights

Conversion of biomass platform molecules into commodity chemicals has received extensive attention owing to the scarcity and high expense of fossil resources [1,2,3,4]
In we report novel nickel based mesostructured carbon materials bearing homogeneously distributed nickel nanoparticles embedded inside the carbonaceous framework synthesized via fabrication of P123-directed chitosan-nickel superamolecular aggregates before pyrolysis
Total selectivity to 1,2-propylene glycol (1,2-PG) and ethylene glycol (EG), and recycling stability are shown when the molar ratio of Ni/CTS in the synthetic gel is 1/2 and the pyrolysis temperature is 550 oC, which can be ascribed to the controlled fabrication of uniform spherical nickel nanoparticles on the mesoporous carbon

Summary

Introduction

Conversion of biomass platform molecules into commodity chemicals has received extensive attention owing to the scarcity and high expense of fossil resources [1,2,3,4] Among this line, the hydrogenolysis of renewable sorbitol to produce high value-added chemicals, like 1,2-propylene glycol (1,2-PG) and ethylene (EG), is a promising green process and is of great demand for producing polymers, resins, pharmaceuticals, cosmetics and functional fluids, etc [5]. The hydrogenolysis of renewable sorbitol to produce high value-added chemicals, like 1,2-propylene glycol (1,2-PG) and ethylene (EG), is a promising green process and is of great demand for producing polymers, resins, pharmaceuticals, cosmetics and functional fluids, etc [5] Various heterogeneous nanocatalysts, such as Ni, Ru, Pd and Pt, have been designed for this process [6,7,8,9]. Recent advances in synthesis of such catalysts focus on wetness
