Investigation of Solid State Diffusion Processes Involved in the Zinc Oxide Sulfidation Reaction

Autor: Olivier Politano, Sébastien Chevalier, Kévin Perrin, Javier Pérez-Pellitero, David Chiche

Publikováno v: Diffusion Foundations. 9:100-110

Sulfidation of undoped and aluminum doped zinc oxide materials has been performed by TGA under a H2S atmosphere in order to evaluate the impact of the doping element on sulfidation reaction kinetics and mechanism. The presence of aluminum seems to sl
