A Landscape of Lignocellulosic Biopolymer Transformations into Valuable Molecules by Heterogeneous Catalysis in C’Durable Team at IRCELYON

Abstract

This review article highlights part of the research activity of the C’Durable team at IRCELYON in the field of sustainable chemistry. This review presents a landscape of the work performed on the valorization of lignocellulosic biopolymers. These studies intend to transform cellulose, hemicellulose and lignin into valuable molecules. The methodology usually consists in evaluating the behavior of the biopolymers in the absence of catalyst under various conditions (solvent, temperature), and then to assess the influence of a catalyst, most often a heterogeneous catalyst, on the reactivity. The most significant results obtained on the upgrading of cellulose and lignin, which have been mainly investigated in the team, will be presented with an opening on studies involving raw lignocellulose.

Preparation of Carbon‐Supported Tungsten Carbides: Comparative Determination of Surface Composition and Influence on Cellulose Transformation into Glycols

“…For that we coupled the results obtained through elaborated characterizations based on XRD and advanced TEM analysis like TEM-EELS mode to get information on the metal sites composition, and particularly on the formation of NiW alloys. The experience of our research group for several years on lignocellulose catalytic valorisation [36][37][38][39][40][41] and on metal carbide catalysts for transformation of biosourced substrates [42,43] enables us to propose this contribution which may help to rationalize the design of related catalytic systems for similar transformations.…”

Tuning the Cu/SiO2 wettability features for bio-derived platform molecules valorization

“…Heterogeneous catalysis has been widely studied in biomass valorization processes due to its versatility and agreement with the Green Chemistry principles, 10,11 as well as to its great success in traditional refinery processes. As known, the heterogeneous catalytic mechanism is a complex process involving several steps and including reagent adsorption and product desorption towards and from the catalyst surface.…”
