Understanding and application of metal–support interactions in catalysts for CO-PROX

Abstract

Preferential oxidation of carbon monoxide (CO-PROX) plays a vital role in H2 purification in the upstream systems of proton exchange membrane fuel cells (PEMFC) for its high efficiency, low cost...

Different metal (Mn, Fe, Co, Ni, and Zr) decorated Cu/CeO2 catalysts for efficient CO oxidation in a rich CO2/H2 atmosphere

“…In recent decades, proton exchange membrane fuel cells (PEMFCs) using hydrogen as a fuel have become the most promising candidate for producing clean electricity because of their advantages such as high efficiency, pollution-free properties, energy conservation, environmental protection, etc. [1][2][3][4] At present, hydrogen is mainly produced by methanol conversion. After water gas transformation, the reforming gas still contained a certain concentration of CO (about 0.5-2%).…”

Double-Edged Sword Effect of Classical Strong Metal–Support Interaction in Catalysts for CO2 Hydrogenation to CO, Methane, and Methanol

“…To date, the application of MSI/SMSI in thermocatalysts and electrocatalysts, − the strategies and inducing mechanisms for SMSI construction (including classical SMSI, oxidative SMSI, adsorbate-mediated SMSI, and wet-chemistry SMSI), ,,− and the characterizations to observe SMSI phenomena , have been partly reviewed. Nevertheless, the “double-edged sword” influence of classical SMSI in CO 2 hydrogenation catalysts has rarely been reviewed in detail.…”
