Beneficial effect of cerium excess on in situ grown Sr_0.86Ce_0.14FeO₃-CeO₂ thermocatalysts for the degradation of bisphenol A.

ABSTRACT: Ce-doped SrFeO₃ perovskite-type compounds are known as good thermocatalysts for the abatement of wastewater contaminants of emerging concern. In this work, Sr_0.86Ce_0.14FeO₃-CeO₂ perovskite-oxide systems with increasing amounts of cerium excess (0, 5, 10 and 15 mol% Ce), with respect to its maximum solubility in the perovskite, were prepared in one-pot by solution combustion synthesis and the effects of cerium excess on the chemical physical properties and thermocatalytic activity in the bisphenol A degradation were evaluated. The powders were characterized by powder X-ray diffraction combined with Rietveld refinement, X-ray photoelectron spectroscopy, thermal gravimetry, temperature programmed reduction, nitrogen adsorption, scanning e
