Jun 26, 2021 The substitution of 0.05 mol La with Pd enhances the activity of the LaMnO3 in CO oxidation. La0.9Pd0.1MnO3 and La0.85Pd0.15MnO3 catalysts exhibit a very high activity, which depends on the conditions of perovskite preparation. Monolithic catalysts display a higher activity during CO oxidation when based on La1xPdxMnO3 than LaMn1xPdxO3 perovskites.
perovskite structure have been recognized as promising catalysts because of their well-defined structures . Voorhoeve et al. reported that the catalytic activities of rare earth manganites and cobaltates are comparable to those of noble metal catalysts for the oxidation of carbon mono-xide, and indicated their use in the control of auto-

A complete process for the light-driven synthesis of carbon monoxide must be based on a sustainable and balanced reaction, consuming only CO 2. To match the reduction of CO 2 at the cathode, an oxidation reaction must occur at the anode, which supplies the electrons consumed in the reduction and regenerates the protons used to accept oxygen ...
