Molecular orientation, which depends on surface coverage, determines whether or not catalytic hydrogenation is chemoselective.

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...

The catalytic properties of Pd and Pt supported on woven glass fabrics were explored for liquid-phase hydrogenation of benzaldehyde as a model for three-phase catalytic reaction. The catalysts demonstrated high activity and are suitable materials to be used in reactors with structured catalytic bed. The main characteristics of catalytic bed are discussed.

he first meso-octaalkylporphyrinogen (calix[4]pyrrole) was synthesized by Baeyer more than 120 years ago, mixing pyrrole and acetone in the presence of an acid. 92 First proposed by Chelintzev et al., the correct structure was definitively proven by Rothemund in 1955, 93, 94 followed forty years later by the X-ray analysis. 95 This macrocycle could be obtained in gram scale and in very good yie...

Abstract This review emphasizes La-based metal oxides of the perovskite form and their application in heterogeneous catalytic transfer hydrogenation (CTH) reactions from year 2013. Perovskites are potential alternatives to noble metals. The possibility induced-synergy between two cations ABO 3 or multicationic perovskites makes them attractive for reactions. Herein, we look at recent developmen...

The catalytic hydrogenation of p-nitrophenol to p-aminophenol was investigated over alumina supported nickel catalysts prepared by impregnation reduction method and mechanical mixing method. The catalysts were characterized by XRD and FESEM. The results show that the nickel particle diameter of alumina supported nickel prepared by impregnation reduction method (denoted as Ni/Al2O3) is slightly ...
