Photoelectrochemical properties of the perovskite BaSnO3 synthetized by chemical route. Application to electro-photocatalytic mineralization of ibuprofen

The perovskite BaSnO3, prepared by chemical route crystallizes in a cubic structure with an average crystallite size of 63 ± 2 nm. The oxide is characterized by scanning electron microscopy, granulometry, optical properties and electrochemistry. The optical properties indicate a direct transition at 3.13 eV. The electrical conductivity follows an exponential law: σo exp (-Ea/kT) due to electronic hopping through mixed valences Sn4+/2+ in agreement with a semi conducting behavior. The intensity potential J(E) curve shows a small hysteresis and exhibits n-type behavior, indicating the presence of oxygen vacancies. The capacitance measurement at pH ～ 5.5 gives a flat band potential of -0.37 VNHE. As application, the ibuprofen is eliminated by electrocatalysis on BaSnO3 with a conversion rate of 55% under a current of 150 mA. An increase up to 68% has been reached by electro-photocatalysis under UV illumination; the ibuprofen disappearance obeys to a first order kinetic with a rate constant of 3 × 10?3 mn?1 and a reaction mechanism is proposed.

The stannonium ion in acid solutions

Stannane reacts slowly with strong aqueous acids below -50° to give 1 mol of hydrogen per mole of stannane. The resulting solutions evolve an additional 2 mol of hydrogen as they are warmed to room temperature. Stannane undergoes a similar, but relatively rapid, reaction with anhydrous fluorosulfuric acid at -78°; when the resulting solution is warmed to room temperature, the solvent is reduced but no hydrogen is evolved. Conductivity studies of the cold undecomposed fluorosulfuric acid solutions indicate the formation of 1 mol of fluorosulfate ion per mole of stannane reacted, and 119Sn nmr spectra of such solutions show a 1:3:3:1 quartet. These results are interpreted in terms of the solvated stannonium ion, SnH3+. Copyright 1971 by the American Chemical Society.
