Kinetics of Strontium Carbonate Formation on a Ce-Doped SrFeO3 Perovskite

Some perovskites exhibit catalytic activity in the abatement of organic pollutants water. However, their performance decreases over time, possibly due to forms poisoning, such as carbonate formation. Here, we present kinetics formation on a Ce-doped SrFeO3 perovskite with formula Sr0.85Ce0.15FeO3?? (SCF), which can act thermocatalyst for degradation pollutants. The was studied air, deionized water, and during bisphenol A. SrCO3 occurred aqueous environments, i.e., when dispersed water or used catalysts A, while no detected samples stored air up 195 days. using both XRD ATR-FT-IR, from XRD, crystallite size found decrease carbonates formed. containing showed an increasing mass loss at >610 °C time showing that SCF reduces its own efficiency use. based TGA measurements approximately three times faster compounds compared is thermally reversible; thus, catalyst resume after heat treatment 900 1 h.
