Co-Precipitated Ni-Mg-Al Hydrotalcite-Derived Catalyst Promoted with Vanadium for CO<sub>2</sub> Methanation

Co-precipitated Ni-Mg-Al hydrotalcite-derived catalyst promoted with vanadium were synthesized with different V loadings (0–4 wt%) and studied in CO<sub>2</sub> methanation. The promotion with V significantly changes textural properties (specific surface area and mesoporosity) and improv...
