Abstract

Hydrotalcite compounds have been successfully prepared by successive infiltrations into the interstices of an ordered array of polystyrene spheres, subsequently removed by either dissolution or thermal decomposition. This method using a template leads to the formation of a three-dimensional open macroporous framework in which the walls are formed by the agglomeration of nanoparticles of two-dimensional hydrotalcite.
