Abstract:
A study of monodisperse Pt/γ-Al2O3 catalysts was carried by XAFS. Key factors of the particle size control were the composition of the precursor solutions and the pretreatment of the carrier. XAFS revealed that variation of preparation methods caused formation of three types of Pt particles (metal, oxide, metal-oxide) located on the γ-Al2O3 surface directly affecting the catalytic activity in CH4 complete oxidation. A method of reliable estimation of the phase composition of the active component is developed taking into account the nano-size effects and Pt oxidation state.
