Abstract The reaction mechanism of plasma‐catalytic ammonia synthesis is not fully understood. MgO supported Ru, Co, Pt, Pd, Cu and Ag catalysts are tested in a DBD plasma at temperature between room 500 °C power 3.8 W 6.4 W. resulting production the presence catalyst can be distinguished into (1) temperature‐independent plasma‐based synthesis, (2) temperature‐dependent synthesis. Turn‐over‐fre...

The activation of oxygen molecules is an important issue in the gold-catalyzed partial oxidation of alcohols in aqueous solution. The complexity of the solution arising from a large number of solvent molecules makes it difficult to study the reaction in the system. In this work, O2 activation on an Au catalyst is investigated using an effective approach to estimate the reaction barriers in the ...

The title reaction is involved in the formation of ammonia in the interstellar medium. We have calculated thermal rates including atom tunnelling using different rate theories. Canonical variational theory with microcanonically optimised multidimensional tunnelling was used for bimolecular rates, modelling the gas-phase reaction and also a surface-catalysed reaction of the Eley-Rideal type. Ins...

The H2O splitting mechanism is a very attractive alternative used in electrochemistry for the formation of O3. The most efficient catalysts employed for this reaction at room temperature are SnO2-based, in particular the Ni/Sb-SnO2 catalyst. In order to investigate the H2O splitting mechanism density functional theory (DFT) was performed on a Ni/Sb-SnO2 surface with oxygen vacancies. By calcula...

This article reports a model study aimed at the detailed description of the mechanism of formation of molecular hydrogen onto dust grain surfaces in the interstellar medium. Using classical trajectories (CT) and quasi-classical trajectories (QCT) calculations, the H2 recombination from the Eley-Rideal process has been studied. This reactive process, involving the collision between one gas phase...
