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

Tuning catalytic reactivity on metal surfaces: Insights from DFT
TL;DR: In this article, density functional theory (DFT) calculations show how catalytic reactivity qualitatively depends on the environment of the active sites, and that new reaction pathways are opened and non-selective pathways through a metallacycle intermediate are disadvantaged.
