标 题 :Process for providing catalytically active platinum metal layers
发明人:BOECKER JUERGEN; BUTZ MICHAEL; FREY ALFRED; HOFMEISTER PETRA; SCHMIDT HANS DIETER
权利人:IBM
摘要:A process for depositing catalytically active platinum metal layers from an ionogenic, acidic, platinum metal ions-containing solution which further contains sulfonic acid. This activation leads to more uniform catalyst layers with greater surfaces which are catalytically more efficient. The process according to the invention can be implemented in any chemical process utilizing platinum metal catalysts, e.g. chemical synthesis, environment applications or metallization of surfaces.
