Resumen:
The effect of incorporating alkaline nitrates in hydrotalcites for use in the combustion of particulate matter from diesel emissions has been studied. The catalysts were characterised by X-ray diffraction (XRD), Adsorption of N2, Scanning Electron Microscopy (SEM), X-ray Photoelectron Spectroscopy (XPS), Elemental Analysis (EA), Atomic Absorption Spectrophotometry (AAS) Temperature Programmed Reduction (TPR) and Fourier Transform Infrared Spectroscopy (FTIR). The activity measurements were carried out with a thermobalance with air and in a fixed-bed reactor with NO/O2 flow. The observed activities showed the following order: HTMgAlcCs > HTMgAlcK > HTMgAlcLi > HTMgAlc.
