Abstract

A series of Ru/TiO₂ catalysts modified by various anions (SO₄²⁻, NO₃⁻, CO₃²⁻, OH⁻, Cl⁻) were prepared by a simple impregnation method. The performance evaluation showed that changing the type of anions of the Ru/TiO₂ catalysts surface realized the complete conversion from CO to CH₄ in CO₂ hydrogenation products, which may be due to the surface anions affecting the adsorption of CO intermediates.
