Correlation Of The Sr-Dopant Content In La1-Xsrxcoo3 With Catalytic Activity For Hydrogen Peroxide Decomposition

La1-xSrxCoO3 (x=0-0.3) samples were prepared by solution combustion method from metal nitrates and alpha-alanineand were characterized by X-ray diffraction (XRD), scanning electron microscopy-energy-dispersive X-ray analysis (SEM-EDX), adsorption isotherms and temperature programmed reduction (TPR). The fractal analysis using adsorption isotherms was performed.The catalytic activity of La1-xSrxCoO3 in H2O2 decomposition as test reaction in alkaline medium was investigated. The kinetic results analysis shows the presence of so-called compensation effect for this group of catalysts.
