Hematite concave nanocubes and their superior catalytic activity for low temperature CO oxidation.
Hematite (α-Fe2O3) concave nanocubes bound by high-index {1344̄} and {123̄8} facets were synthesized and their catalytic activity for CO oxidation were also investigated.
متن کاملWater-enhanced low-temperature CO oxidation and isotope effects on atomic oxygen-covered Au(111).
Water-oxygen interactions and CO oxidation by water on the oxygen-precovered Au(111) surface were studied by using molecular beam scattering techniques, temperature-programmed desorption (TPD), and density functional theory (DFT) calculations. Water thermally desorbs from the clean Au(111) surface with a peak temperature of approximately 155 K; however, on a surface with preadsorbed atomic oxyg...
متن کاملAu/CeO2 Catalysts: Structure and CO Oxidation Activity
In this comprehensive review, the main aspects of using Au/CeO2 catalysts in oxidation reactions are considered. The influence of the preparation methods and synthetic parameters, as well as the characteristics of the ceria support (presence of doping cations, oxygen vacancies concentration, surface area, redox properties, etc.) in the dispersion and chemical state of gold are revised. The prop...
متن کاملAtomically Dispersed Pd–O Species on CeO2(111) as Highly Active Sites for Low-Temperature CO Oxidation
Ceria-supported Pd is a promising heterogeneous catalyst for CO oxidation relevant to environmental cleanup reactions. Pd loaded onto a nanorod form of ceria exposing predominantly (111) facets is already active at 50 °C. Here we report a combination of CO-FTIR spectroscopy and theoretical calculations that allows assigning different forms of Pd on the CeO2(111) surface during reaction conditio...
