Abstract
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.
Claims17
A process for depositing metallic material onto a substrate surface, comprising the steps of:
- a.) providing an activator compound homogeneously distributed in a solvent, the activator compound being an ionogenic compound capable of releasing platinum metal ions, the solvent including an organic or inorganic acid;
- b.) adding an anionic surfactant to the solution provided in step a.), the anionic surfactant being a sulfonic acid;
- and
- c.) applying the solution provided in step b.) to said surface, whereby catalytically active platinum metal is deposited onto said surface.
