Alumina (Al2O3) is a widely used material for catalysis in the chemical industry. Besides high specific surface area, acid sites on Al2O3 play crucial role transformation of adsorbed molecules, which ultimately react and desorb from catalyst. This study introduces synthetic method based electrospinning to produce nanofibers (ANFs) with acidity porosity tuned using different aluminum precursor f...

The development of methodologies for regioselective C–H functionalization N-heterocycles has seen sustained growth over the last two decades. Cooperative reactivity stemming from addition Lewis-acidic metals to late-transition-metal complexes enabled catalytic transformations. Progress in design ligands and metal precursors led situ cooperative catalysts able facilitate pyridine at C-2, C-3, C-...

group viii b metal oxides supported on gamma-alumina were investigated as catalysts and promoters of moo3 hydrodesulfurization catalysis. superior promotion was observed in pbo promoted catalyst compared to that of coo, the typically accepted promoter. other metal oxides, sno and ho2o3 exhibited reasonable hydrodesulfurization catalysis promotion but lower than for coo promoted catalyst.

During the study of the acid hydrolysate of a polysaccharide from BtiZZus subtilis (3), the hexosamine fraction (4) was found to give an unidentified spot on paper chromatograms. Its color reactions were typical for an amino sugar, but it moved at a faster rate than glucosamine or galactosamine. Furthermore, degradat,ion with ninhydrin (5) afforded a reducing product possessing a RF higher than...

The main interaction between pyridine and zeolites leads to form a hydrogen bond between the N atom of pyridine and OH groups of zeolites. The present work reports a theoretical study about the structural, vibrational and topological properties of the charge distribution of the molecular complexes between pyridine and a series of acids sites of zeolites. The calculated structural parameters...
