Heteropoly Acid-Based Catalysts for Hydrolytic Depolymerization of Cellulosic Biomass.

Cellulose is the most abundant source of biomass, which can be converted into monosaccharide or other chemical platform molecules for the sustainable production of chemicals and fuels. Acid catalysts can promote hydrolytic degradation of cellulose into valuable platform molecules, which is of great significance in the development of chemicals and biofuels. However, there are still some shortcomings and limitations of the catalysts for the hydrolytic degradation of cellulosic biomass.

Recent advances in liquid hydrosilane-mediated catalytic -formylation of amines with CO.

Carbon dioxide is an ideal raw material for the synthesis of complex organic compounds because of its rich, non-toxic, and good physical properties. It is of great significance to transform CO into valuable fine chemicals and develop a green sustainable cycle of carbon surplus. Based on hydrosilane as a reducing agent, this work summarizes the recent applications of reductive amidation of CO using different catalysts such as organocatalysts, ionic liquids (ILs), salts, transition metal complexes, and solvents.
