Thermal decomposition of ammonium perchlorate catalyzed with CuO nanoparticles

Defence Technology, 2019
Ammonium perchlorate (APC) is the most common oxidizer in use for solid rocket propulsion systems. However its initial thermal decomposition is an endothermic process that requires 102.5 J·g−1. This manner involves high activation energy and could render

Recovered carbon black from tires as carbon carrier in metal oxide catalytic systems

South African Journal of Chemical Engineering
Pyrolysis is one of the most common methods of end-of-life tires (ELTs) recycling. This study considered the use of carbon black from pyrolysis of ELTs as a carbon carrier for metals (Co, Ni, Cu, Fe) and their oxides to produce catalytic systems.
