| Abstract: | Strontium
zirconate (SrZrO3) has been synthesized by solution combustion
synthesis method using mixture of fuels, such as glycine, urea and ammonium
nitrate, and corresponding metal nitrates as oxidizer. It has been characterized
by XRD, electrical conductivity, diffuse reflectance spectra, TGA and DTA
analysis, surface area and powder density measurements. Surface area, measured
by Brunquer-Emmett-Teller method, has
a value of 15.34 m2 g-1. Particle size is calculated using
values of surface area and powder density, which has a value of 56 nm. The
SrZrO3 powders thus synthesised have been used as a catalyst for the
decomposition of H2O2 at two different temperatures.
Activation energy has been found to be 290 Cal.mol-1, suggesting the
occurrence of chemisorption. |
