Rapid Discrimination of Adsorbed Oxygen and Lattice Oxygen in Catalysts by the Cataluminescence Method

Analytical Chemistry, 2022
Adsorbed oxygen and lattice oxygen are crucial parameters for catalyst characterization and catalytic oxidation mechanism. Therefore, rapid discrimination of adsorbed oxygen and lattice oxygen is highly desired. Herein, a direct correlation between cataluminescence (CTL) kinetic curve and oxygen species was discovered. The adsorbed oxygen-catalyzed CTL

Effects of the surface adsorbed oxygen species tuned by rare-earth metal doping on dry reforming of methane over Ni/ZrO2 catalyst

Applied Catalysis B: Environmental, 2020
During dry reforming of methane, oxygen species over the catalyst surface play an important role in CH4/CO2 reactivity, catalytic performance and carbon deposition. Herein, the effects of the surface adsorbed oxygen species tuned by doping with different

Discovering the key role of MnO2 and CeO2 particles in the Fe2O3 catalysts for enhancing the catalytic oxidation of VOC: Synergistic effect of the lattice oxygen species and surface-adsorbed oxygen.

Science of the Total Environment, 2022
Highly active mesoporous Fe-Mn-Ce catalysts with high specific surface area (SBET) were synthesized by a modified precipitation process for catalyzing toluene oxidation. The Fe0.85Mn0.1Ce0.05 catalyst presents richer surface oxygen species (OS), a higher

Photoemission studies of adsorbed oxygen and oxide layers

Surface Science Reports, 1982
Abstract A comprehensive review is given about the enormous versatility of photoelectron spectroscopy to study the especially complex interaction of oxygen with metal surfaces and the nature of the reaction products. The great variety of well definable parameters of a photoemission experiment, e.g.
