PURPOSE: A catalyst for reforming methane with enhanced stability for sulfur components, a preparing method of the same, and a methane reforming method using the same are provided to show superior catalytic activity and stability in a methane reforming reaction using by-product gas containing sulfur, specifically hydrogen sulfide. CONSTITUTION: A catalyst carries 0.2-5 parts by weight of rhodium based on 100 parts by weight of a CeO2-ZrO2 support. The specific surface area of the catalyst is 20-50 m^2/g. The specific surface area of the CeO2-ZrO2 support is 20-80 m^2/g. The weight ratio of CeO2/ZrO2 is 0.3-4.0. The catalyst is used for a methane reforming reaction using by-product gas containing 3000ppmv or less of H2S. A preparing method of the catalyst includes the steps of: carrying 0.2-5 parts by weight of rhodium in 100 parts by weight of CeO2-ZrO2 support based on the content of metals; and plasticizing at a temperature between 400 and 800C.
