Abstract

Synthesis of cobalt (II) and Ni (II) complexes of lauroyl-glycylglycine in the presence of montmorillonite-silica nanowires was followed in terms of variable morphologies induced by self-assembling phenomena. The interactions between different metal complexes and the montmorillonite-silica nanowires segments were observed by FTIR, TGA, DSC and SEM results. These interactions induced variable morphologies (sheet-like, ribbon-like, tube-like and fiber-like). Variable morphologies, physical and chemical nature and the thermal stability recommend this new class of hybrids in catalysis applications..
