Reduction of surface oxide preformed on unsupported and alumina supported Cu-Ni alloys was examined at a linearly increasing temperature. The obtained TPR spectra exhibited two peaks of H2 consumption, connected with the reduction of surface copper and surface nickel oxides. The size of these peaks was used to estimate surface compositions of the alloy. The results obtained agree with the surface composition calculated from a semiempirical equation.
