Hydrogen production from propane steam reforming over Ir/Ce 0.75 Zr 0.25 O 2 catalyst

Structure, synthesis, and catalytic properties of nanosize cerium-zirconium-based solid solutions in environmental catalysis

“…(63) and (64) [503][504][505]. The OSC and redox properties of a cerium-based oxygen storage material are closely related to the oxygen vacancy concentration, migration rate of oxygen vacancy, surface area, and the formation of anion defects [506,507]. The lattice defects formed in the bulk of CZO can make the bulk lattice oxygen and oxygen vacancies to be used in catalytic reaction, but the OSC and thermal stability still can not meet the ever increasingly stringent emission standards.…”

Hydrogen production from ethanol over Ir/CeO2 catalyst: Effect of the calcination temperature

“…The highly dispersed tiny particles not only facilitated C-C bond dissociation but inhibited the coke formation, which might result in the irreversible catalyst deactivation and/or the increase of catalytic bed pressure [18,19]. It is generally accepted that support also plays a critical role in catalyst activity and stability for ethanol reforming [20,21]. Kugai et al [22] indicated that CeO 2 support significantly affected both the geometric (e.g., metal dispersion) and electronic (e.g., metal-support interaction) properties of the supported NiRh bimetallic catalysts for ethanol OSR reaction.…”

Catalytic Production of Glycolic Acid from Glycerol Oxidation: An Optimization Using Response Surface Methodology

“…Likewise, the proportion of Ce 3+ and Ce 4+ with respect to total cerium was calculated ( Table 2), finding that for the Ce0.75Zr0.25O2 support there was 83.2% of Ce 4+ , and for 5%Ag/Ce0.75Zr0.25O there was 82%. This may suggest oxygen vacancies or O atoms relaxations resulting from silver deposition [25,26]. Figure 4 shows the XPS spectra of Ce0.75Zr0.25O2 support and 5%Ag/Ce0.75Zr0.25O2 catalyst for O1s, Zr 3d, and Ag 3d peaks.…”
