Kinetics of interaction between nanocrystalline SnO2〈M〉 (M = In, Fe, Ru, Ce) and oxygen
The rate of interaction between nanocrystalline SnO 2 〈M〉 (M = In, Fe, Ru, Ce) and oxygen is studied using in situ electrical conductivity measurements. The process kinetics are analyzed in terms of the diffusion-reaction model. The results indicate that doping of tin dioxide with ruthenium, cerium,...

〈M〉 (M = In, Fe, Ru, Ce) and oxygen is studied using in situ electrical conductivity measurements. The process kinetics are analyzed in terms of the diffusion-reaction model. The results indicate that doping of tin dioxide with ruthenium, cerium, iron, and indium oxides reduces the rate constant of the reaction between SnO

and oxygen and raises the activation energy for this process. |
