CATALYST PROPERTY CONTROL WITH INTERMIXED INORGANICS

摘要

Nanostructured thin film catalysts which may be useful as fuel cell catalysts are provided, the catalyst materials including intermixed inorganic materials. In some embodiments the nanostructured thin film catalysts may include catalyst materials according to the formula PtxM(1−x) where x is between 0.3 and 0.9 and M is Nb, Bi, Re, Hf, Cu or Zr. The nanostructured thin film catalysts may include catalyst materials according to the formula PtaCobMc where a+b+c=1, a is between 0.3 and 0.9, b is greater than 0.05, c is greater than 0.05, and M is Au, Zr, or Ir. The nanostructured thin film catalysts may include catalyst materials according to the formula PtaTibQc where a+b+c=1, a is between 0.3 and 0.9, b is greater than 0.05, c is greater than 0.05, and Q is C or B.
