Grothuss vs vehicle mechanisms
WebThe Grotthuss mechanism is very similar to Li+ conductivity through segmental motions as it relies on the rate of polymer reorganization, while the vehicle mechanism is governed by the rate of physical diffusion of the vehicle. WebDec 1, 2016 · Possible mechanisms of proton conduction in AlPO-PC-1 (a) at 25–100 °C following the Grotthuss mechanism in which the proton-hopping along the hydrogen bonding network dominates the proton conduction and (b) at 115–150 °C following both the vehicle and Grotthuss mechanisms in which the hydronium ions and imidazole ions …

WebProton Hopping in water is the process of diffusion of protons (H⁺ ions) through the network of hydrogen-bonded water molecules in the liquid water. Proton hopping is also called as Grotthuss mechanism, named after the discoverer Theodor Grotthuss.The net result of proton hopping is the fast movement of H⁺ ions in water than any other … WebOct 7, 2014 · Such behavior contrasts with that of a material conducting protons through structural diffusion or vehicle mechanisms (SPES), in which the peaks in both (2)H and …
