Air-Stable and Reusable Cobalt Phosphide Nanoalloy Catalyst for Selective Hydrogenation of Furfural Derivatives

A highly selective and stable ZnO-ZrO2 solid solution catalyst for CO2 hydrogenation to methanol

Although methanol synthesis via CO hydrogenation has been industrialized, CO2 hydrogenation to methanol still confronts great obstacles of low methanol selectivity and poor stability, particularly for supported metal catalysts under industrial conditions. We report a binary metal oxide, ZnO-ZrO2 solid solution catalyst, which can achieve methanol selectivity of up to 86 to 91% with CO2 single-p...

Air-stable and phosphine-free iridium catalysts for highly enantioselective hydrogenation of quinoline derivatives.

Enantioselective hydrogenation of quinoline derivatives catalyzed by phosphine-free chiral cationic Cp*Ir(OTf)(CF 3TsDPEN) complex (CF 3TsDPEN = N-(p-trifluoromethylbenzenesulfonyl)-1,2-diphenylethylene-diamine) afforded the 1,2,3,4-tetrahydroquinoline derivatives in up to 99% ee. The reaction could be carried out with a substrate-to-catalyst molar ratio as high as 1000 in undegassed methanol a...

Catalyst Development for Selective Hydrogenation of Functionalized Alkynes and Nitroarenes

Microwave‐Assisted Selective Hydrogenation of Furfural to Furfuryl Alcohol Employing a Green and Noble Metal‐Free Copper Catalyst

Green, inexpensive, and robust copper-based heterogeneous catalysts achieve 100 % conversion and 99 % selectivity in the conversion of furfural to furfuryl alcohol when using cyclopentyl-methyl ether as green solvent and microwave reactors at low H2 pressures and mild temperatures. The utilization of pressurized microwave reactors produces a 3-4 fold increase in conversion and an unexpected enh...

Effect of Calcination Rate on Performance of Co-precipitated Cu-MgO Catalyst in Hydrogenation of Furfural

Co-precipitated Cu-MgO catalysts were prepared and evaluated for the gas-phase hydrogenation of furfural. The effect of heating rate at the calcination step was studied by comparing the performance of three catalysts prepared via the same procedure but calcined at different heating rates. The results established that altering the heating rate could influence the structural properties of the cat...
