Abstract
A non-pyrophoric shift reaction catalyst includes an oxide carrier impregnated with platinum (Pt) and cerium (Ce). The non-pyrophoric shift reaction catalyst may be prepared by uniformly mixing a platinum precursor, a cerium precursor, and an oxide carrier in a dispersing medium to obtain a mixture; drying the mixture; and calcining the dried mixture. The shift reaction catalyst having a non-pyrophoric property has an excellent reaction activity even at a low temperature and can efficiently remove carbon monoxide in fuel.
