A series of iron-,copper-,zinc-,cerium-,magnesium-and aluminum-containing ternary and quaternary hydrotalcite-like compounds were prepared by coprecipitation and characterized by XRD and N2 adsorption-desorption.All samples prepared were calcined at 700℃ for 6 h to obtain metal complex oxides whose structure and SO2 redox performance were measured in a modified WRP-3 thermal balance.The results showed that zinc was not effective for redox of SO2 and copper was an efficient promoter for oxidization of SO2 to...
