V2O5/SiO2 catalyst was utilized to oxidize SO2 to SO3 species in the presence of oxygen mainly for producing sulfuric acid. For this catalyst, the active phase was a mixture of vanadium pentoxide and basic sulfate/pyrosulfate material. This active phase at the reaction temperature behaved as a liquid filling up the pores of the silica support. On the other hand, amounts of the SO3 and V5+ speci...

In this study, the electrooxidative carbon nanotube (CNT) filtration of sorptive methyl orange (MO) and non-sorptive ferrocyanide was investigated by both experiment and numerical simulation. The two-dimensional numerical model includes target molecule; mass transport, adsorption, and electron transfer and product desorption. For MO, the model was calibrated with experimental reaction rates fro...

The inversion of the Oh-Model is based on the solution of relations introduced in the former paragraph. In the absence of an analytic solution, ks and ε ′ have to be estimated by an iterative procedure. In a first step, Γ° is evaluated from 0 1 23. 0 1 2 1 = − +       ° Γ       ° Γ p q π θ (1) Using the measured co-and cross-polarised ratios, Γ° can be estimated from (1) using an it...

Purely ionic electrolytes—wherein liquids replace neutral solvents—have been proposed to improve lithium-ion-battery performance, on the basis that unique microscopic characteristics of polarized ionic-liquid/electrode interfaces may selectivity and kinetics interfacial lithium-exchange reactions. Here we model a “three-ion” ionic-liquid electrolyte, composed traditional liquid lithium salt wit...
