Abstract
Platinum black is electrochemically plated onto a conductive substrate, such as a platinum electrode, by positioning a counter electrode and the conductive substrate in a platinum(IV) ion plating solution. An electric current is passed through the counter electrode, substrate and plating solution for a predetermined period of time. The plating solution and conductive substrate are subjected to ultrasonic agitation while the plating is carried out. The plating solution preferably includes chloroplatinic acid and lead ion.
