STM conductance spectroscopy and mapping has been used to analyze the impact of molecular adsorption on the quantized electronic structure of individual metal nanoparticles. For this purpose, isophorone and CO2, as prototype molecules for physisorptive and ...
We demonstrate that the kinetics of the Sabatier reaction catalysed by sorption catalysts depends on the nanostructure of the catalyst-sorbent system. The catalysts are prepared by ion exchange of a nickel nitrate solution in two zeolites with different po ...
The hydrogen sorption pathways of alkali alanates were analyzed and a mechanism for the catalytic hydrogen sorption was developed. Gibbs free energy values of selected intermediate steps were calculated based on experimentally determined thermodynamic data ...
We report on the growth of palladium nanoparticles on the basal plane of as-cleaved highly oriented pyrolytic graphite (HOPG) samples, and on CO2 ion sputtered nanostructured HOPG surfaces. The morphology of Pd nanostructures grown at room temperature is i ...
The reduction of protons into dihydrogen is important because of its potential use in a wide range of energy applications. The preparation of efficient and cheap catalysts for this reaction is one of the issues that need to be tackled to allow the widespre ...
Catalytic activity of perovskites for oxygen reduction (ORR) was recently correlated with bulk d-electron occupancy of the transition metal. We expand on the resultant model, which successfully reproduces the high activity of LaMnO3 relative to ...
The promoting effect of Zn on Pt-based catalyst was studied for the liquid-phase hydrogenation of 3-nitrostyrene (3-NS). The monodispersed Pt nanoparticles (ca. 2.3 nm) supported on ZnO catalyzed the target 3-vinylaniline (3-VA) formation (S3-VA = 97% at X ...
The reaction of propargyl amines with tert-butylisonitrile in the presence of a catalytic amount of both Yb(OTf)3 and AgOTf afforded imidazoles, whereas the same reaction with primary and secondary alkylisonitriles, as well as arylisonitriles, in the prese ...
The catalytic properties of Pd have triggered a strong interest in the related catalysis by Au–Pd nanoparticles. However, the analysis of such phenomena has been complicated so far due to the presence of capping. Using X-ray irradiation, we produced uncapp ...
Using density functional theory, we systematically compute and investigate the binding enthalpies of 14 different small molecules in a series of isostructural metalorganic frameworks, M-MOF-74, with M = Mg, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn. The small ...
