Hydrogenolysis Goes Bio: From Carbohydrates and Sugar Alcohols to Platform Chemicals
TLDR
Past and present developments in hydrogenolysis reactions are highlighted, with special emphasis on the direct utilization of cellulosic feedstocks, to bridge currently available technologies and future biomass-based refinery concepts.Abstract:
In view of the diminishing oil resources and the ongoing climate change, the use of efficient and environmentally benign technologies for the utilization of renewable resources has become indispensible. Therein, hydrogenolysis reactions offer a promising possibility for future biorefinery concepts. These reactions result in the cleavage of C-C and C-O bonds by hydrogen and allow direct access to valuable platform chemicals already integrated in today's value chains. Thus, hydrogenolysis bears the potential to bridge currently available technologies and future biomass-based refinery concepts. This Review highlights past and present developments in this field, with special emphasis on the direct utilization of cellulosic feedstocks.read more

Some insight into the role of different copper species as acids in cellulose deconstruction
TL;DR: In this article, supported copper catalysts have been tested in cellulose hydrolysis and compared with the corresponding bare supports and showed an increase in both conversion and selectivity to lactic acid due to the combination of Lewis and Bronsted acidic sites.

Highly Efficient and Recyclable Catalysts for Cellobiose Hydrolysis: Systematic Comparison of Carbon Nanomaterials Functionalized With Benzyl Sulfonic Acids.
Samuel Carlier,Sophie Hermans +1 more
TL;DR: It is found that a minimum threshold amount of acidic functions is required for triggering the hydrolysis of cellobiose and the selectivity toward glucose is very high as soon as sulfonic functions are present on the catalyst.
