The present research focuses on a Ni-Mg-Al hydrotalcite-derived catalyst promoted with Cu. Catalysts were prepared by the co-precipitation method at constant pH and subsequently characterized via XRD, H2-TPR, CO2-TPD, TGA, XAS, TEM, low-temperature nitrogen sorption tested for CO2 hydrogenation to methane. methanation reaction was carried out GHSV of 12,000 ml?g-1 h-1 high selectivity (above 98...
