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

Understanding the active copper sites of Cu/ZrO2 catalyst applied to direct conversion of ethanol to ethyl acetate and hydrogen
TL;DR: In this paper, the origin and influence of active sites on supported copper catalysts and their catalytic properties for ethanol conversion were investigated using infrared Fourier transform spectroscopy of adsorbed CO and showed that Cu 1+ was more prevalent than Cu 0 species at the Cu/SiO2 surface, and that Cu 0 was the main species on Cu/ZrO2.
