(544gq) Effect of Lanthanum and Chlorine Doping on Strontium Titanates for the Electrocatalytically-Assisted Oxidative Dehydrogenation of Ethane
Strontium titanate-type perovskites were synthesized using a modified Pechini method. Synthesized materials were characterized using XRD, XPS, Four probe DC van der Pauw conductivity, RAMAN, DRIFTS and temperature-programmed oxidation with CO2 techniques to study their bulk and surface structural properties and electrical/ionic mobility.
Electrochemical activity experiments were performed at 600Â°C in the current density range 0-3.5 mAcm-2. The activity results showed that lanthanum doping of strontium titanate improves ethane conversion, and additional chlorine incorporation into the perovskite structure enhances both ethane conversion as well as selectivity towards ethylene .
