Abstract (en)

[origin: WO9909234A2] In one embodiment, the present invention relates to a method of making a catalytic film comprising: applying an electric current to an electrochemical cell comprising an anode, a cathode and a solution comprising a film forming compound and a nitrate ion source thereby forming the catalytic film. In another embodiment, the present invention relates to a method of preparing a hydroxylammonium salt, involving the steps of: providing an electrochemical cell containing an anode, a cathode, and a divider positioned between the anode and the cathode, to define a catholyte compartment between the cathode and the divider and an anolyte compartment between the anode and the divider; charging the catholyte compartment with a first solution comprising a nitrogen containing compound and a mediator and the anolyte compartment with a second solution comprising an ionic compound; passing a current through the electrochemical cell to produce a hydroxylammonium salt in the catholyte compartment; and recovering the hydroxylammonium salt from the catholyte compartment.
