A Stepwise Control Route for the Preparation of Mg-Al,Zn-Al,and Mg-Fe Layered Double Hydroxides (LDHs)

摘要：

　　Mg-Al,Zn-Al,and Mg-Fe layered double hydroxides (LDHs) have been synthesized through a stepwise control route.In the stepwise control route,we controlled the state of Al or Fe composition as Al or Fe hydroxyl aqueous complexes in aqueous solution first,then dropwise Mg2+ or Zn2+ and OH-and keep procedure at constant pH value simultaneously at room temperature.The textural and structure properties of the resulting samples were characterized by XRD and TG-DTG.The results showed that products obtained by the stepwise control route were pure and highly crystalline LDHs.The particle size and size distribution was measured by DLLS.
