Abstract
Improved electrolytic processes employing oxygen anodes. The improvement comprises the step of conducting a electrolysis process in an electrolytic cell having a platinum based amorphous metal alloy oxygen anode having the formula Pt.sub.p A.sub.a D.sub.d where A is Cr, Mo, W, Fe, Os, Ir, Cu, Ni, Rh, Pd, Ag, Ti, Ru, Nb, V, Ta, Au and mixtures thereof; D is B, C, Si, Al, Ge, P, As, Sb, Sn and mixtures thereof; p ranges from about 40 to 92; a ranges from about 0 to 40; and d ranges from about 8 to 60, with the proviso that p+a+d=100.
Claims27
Improved electrolytic processes where oxygen is generated at the anodes, the improvement comprising the step of:
- conducting said electrolysis process in an electrolytic cell having a platinum based amorphous metal alloy oxygen anode having the formula
- Pt.sub.p A.sub.a D.sub.d
- where
- A is one or more elements selected from the group consisting of Cr, Mo, W, Fe, Os, Ir, Cu, Ni, Rh, Pd, Ag, Ti, Ru, Nb, V, Ta and Au;
- D is one or more elements selected from the group consisting of B, C, Si, Al, Ge, P, As, Sb and Sn;
- p ranges from about 40 to 92;
- a ranges from about 0 to 40;
- and
- d ranges from about 8 to 60, with the provisos that p+a+d=100 and when D is Si or P, and A does not include Ir, Rh, Pd, Ti, Ru, Nb or Ta.
