Catalytic Co-Conversion of CH₄ and CO₂ Mediated by Rhodium-Titanium Oxide Anions RhTiO₂.

ABSTRACT: Catalytic co-conversion of methane with carbon dioxide to produce syngas (2 H₂ +2 CO) involves complicated elementary steps and almost all the elementary reactions are performed at the same high temperature conditions in practical thermocatalysis. Here, we demonstrate by mass spectrometric experiments that RhTiO₂ ^- promotes the co-conversion of CH₄ and CO₂ to free 2 H₂ +CO and an adsorbed CO (CO_ads ) at room temperature; the only elementary step that requires the input of external energy is desorption of CO_ads from the RhTiO₂ CO^- to reform RhTiO₂ ^- . This study not only identifies a promising active species for dry (CO₂ ) reforming of methane to syn
