英文摘要	nominal composition of zr-ni co-doped ba2co2fe12-2x(zr,ni)(x)o-22 (x = 0.2-1.0) y-type hexaferrites were synthesized by conventional sol gel and microwave heating methods. structural analysis was carried out by tga, sem, xrd, o-2-tpd and bet surface area. microwave synthesized samples revealed good morphological properties with high surface area and high porosity compared to that obtained by the sol-gel method. catalytic decomposition of n2o was achieved at low temperatures of 600 degrees c and 700 degrees c for microwave and sol gel prepared samples, respectively. the catalysts are found workable and stable even at 1146 degrees c with very good n2o decomposition efficiency. substituting iron with zr ni further enhanced the catalytic activity in both the cases.
