Les catalyseurs en toile de platine-rhodium utilisés au cours de la fabrication de l'acide nitrique sont l'objet de processus de reconstruction de surface étendus. Ceci a été examiné à l'aide d'un réacteur catalytique miniature et de techniques telles que la sonde à atomes (AF-PIM), la microscopie électronique, et les rayons X. Un mécanisme impliquant le transport en phase vapeur est proposé pour expliquer les principaux traits de la variation du comportement du catalyseur dans les conditions opératoires.Platinum-rhodium gauze catalysts used in the manufacture of nitric acid undergo an extensive surface reconstruction process.
