Effect of CTAB Concentration on Synthesis and Sensing Properties of Perovskite Oxide via a Hydrothermal Process

Abstract:

La_0.7Sr_0.3FeO₃ materials with morphologies including nanoparticles, nanorods and nanowires were synthesized via a hydrothermal process assisted with different cetyltrimethyl ammonium bromide (CTAB) concentration. XRD, SEM and BET were used to characterize the morphology, composition and structural properties of the nanomaterials. The effect of CTAB concentration on morphology and growth mechanism of La_0.7Sr_0.3FeO₃ was discussed. The gas sensing properties of La_0.7Sr_0.3FeO₃ materials with different morphologies were also carried out in 0.1~ 100 ppm formaldehyde.
