Description Hot Isostatic Pressure (HIP) process has been used for the first time to
synthesize SrRuO3 type perovskite. The syntheitc material shows the formation
of highly crystalline and pure phase, which is often difficult to achieve due to
Ru volatalization during synthesis, also leading to the formation of undesired
phases. The catalytic properties of this material have been studied for methane
combustion reaction which infer good catalytic activity of this catalyst. SrRuO3
appears to follow a suprafacial mechanism through dissociative adsorption of
oxygen, while strontium may also be contributing towards the weakening of
Ru-0 bond of the adsorbed oxygen, to facilitate the catalytic activity for this
reaction. The catalyst shows very high thermal stability, which otherwise is a
limitation with ruthenium based catalytic materials. HIP therefore, can be
especially useful to synthesize catalytic materials based on volatile component
like ruthenium, which can be thermally stabilized in perovskite type structure
