Abstract

Pt/charcoal catalysts with platinum contents in the range 1.2–11.3 wt%, as used in a slurry reactor for the production of hydroxylamine by hydrogenation of nitric oxide in a sulfuric acid environment, have been microstructurally characterized by small angle X-ray scattering, line-broadening analysis of wide angle X-ray scattering profiles, and transmission electron microscopy. The microstructural data are related to the results of chemisorption analysis and to the catalytic rates of hydroxylamine production, giving a better insight into the catalytic process.
