Characterisation of Robust Combustion Catalyst from Aluminium Foil Waste

Herein a robust and active combustion catalyst was prepared with three-quarter (75 wt.%) of its composition derived from the aluminium foil waste and designated as 5Pd-ACFL. The prepared catalyst was characterised using X-ray diffraction (XRD), Temperature-programmed reduction (TPR), Bright-field transmission electron microscopy (BF-TEM), High angle annular dark field (HAADF), Fourier transform infrared-pyridine (FTIR-Pyridine) and X-ray Photoelectron Spectroscopy (XPS) techniques and compared to the commercial equivalent (5Pd-AC550). The catalyst 5Pd-ACFL550 showed higher catalytic activity than that of 5Pd-AC550 in the total methane oxidation reaction with T50% at 303 ºC at Gas hourly space velocity (GHSV) of 100,000 mL g-1 h-1. Our approach opens doors for the preparation of robust cheap combustion catalyst from aluminium foil waste and demonstrates its application in the catalytic converters of natural gas vehicles (NGV-vehicles) and other combustion applications. As a result, this can be opened up to a wider variety of application markets, including residential and automotive applications.
