摘要：

Various layered double hydroxides (LDHs) consisting of magnesium and a trivalent metal (Al, Ga or In) in an Mg/M(III) ratio of 3 were prepared by precipitation from the corresponding nitrates and also from magnesium ethoxide and the acetylacetonates of the trivalent metals using the sol-gel method. The six LDHs thus obtained were calcined at 500degreesC. All solids were characterized by XRD and IR spectroscopy prior to and after calcination. Their textural properties were determined from nitrogen adsorption measurements and their surface chemical properties by CO2 chemisorption. (C) 2002 Elsevier Science (USA).
