Abstract:
1. A methanol oxidation catalyst comprising: nanoparticles having a composition represented by the following formula 1: where T is at least one selected from the group consisting of W and V, x is 20 to 80 at. %, y is 10 to 60 at. %, z is 1 to 30 at. % and u is 1 to 30 at. %, wherein the catalyst shows a peak derived from an oxygen bond of T and a peak derived from a metal bond of T in a spectrum measured by an X-ray photoelectron spectral method, and wherein the area of the peak derived from the oxygen bond of T is 80% or less of the area of the peak derived from the metal bond of T.
