Abstract
The thermal decomposition of hydrogen peroxide (H2O2) as green energetic material has been performed over free noble metal-synthesized catalysts. A mass percent of 30% (w/w) H2O2 liquid has been decomposed over 1wt.% of solid catalysts based on copper, cobalt and chromium metals. In this research work, the catalytic performance of the thermal decomposition of H2O2 was carried out by measuring the differential pressure (P) versus time at initial constant temperatures and for first time by DTA-TG technique at atmospheric pressure. The obtained preliminary results showed that copper-based is subsequently promising catalyst for the decomposition of H2O2 liquid solution. Moreover, the SEM microscopy technique was used to characterize the solid surfaces in order to understand the morphological characteristics of the solids.
