Ethanol synthesis catalytic CO hydrogenation over multi-elemental KFeCuZn/ZrO catalyst.

Technological enablers that use CO as a feedstock to create value-added chemicals, including ethanol, have gained widespread appeal. They offer a potential solution to climate change and promote the development of a circular economy. However, the conversion of CO to ethanol poses significant challenges, not only because CO is a thermodynamically stable and chemically inert molecule but also because of the complexity of the reaction routes and uncontrollability of C-C coupling.

Mechanism of NH-SCR over P/CeO Catalysts Investigated by Spectroscopies.

This study reports a comprehensive investigation into the active sites and reaction mechanism for the selective catalytic reduction of NO by NH (NH-SCR) over phosphate-loaded ceria (P/CeO). Catalyst characterization and density functional theory calculations reveal that HPO and HPO species are the dominant phosphate species on the P/CeO catalysts under the experimental conditions. The reduction/oxidation half-cycles (RHC/OHC) were investigated using X-ray absorption near-edge structure for Ce L-edge, ultraviolet-visible, and infrared (IR) spectroscopies together with online analysis of outlet products ( spectroscopy).
