Nevertheless, the results were contrasted with those of pure SnO 2 in order to comprehend the impact of Ce doping. Carbonaceous material was discovered to have been deposited on the catalyst’s surface after the reaction, as a by-product and was characterized through several analytical techniques. To further explore the impact on the pyrolysis reaction, the reaction parameters were altered in terms of temperature, heating rate, and catalyst amount. Maximum H 2 production of 34.793 mg/g PP has been achieved with an optimized temperature of 500 ºC and a heating rate of 10 o C per minute with a plastic:catalyst ratio of 2:5. The research enlightens the beauty of doped SnO 2 to carry out hydrocarbon cracking sustaining the pyrolytic conversion of plastic at lower temperature into value added products by lowering the activation energy needed for the process.
