Chiral polyoxometalates (POMs)-based materials have attracted particular attention in recent years due to their remarkable properties and potential application, especially in the field of catalysis. The goal of this thesis is to design a series of enantiopure nanohelical structures based on polyoxometalates (NANOPOM), for their use as heterogeneous oxidation catalysts. Two approaches were used to prepare these new materials. The first one based on the immobilization of POMs on silica nanohelices and nanoribbons by electrostatic and direct adsorption grafting. These inorganic structures increase the stability and make them less sensitive to external environment. The second approach is to include POM units within the structure of organic nano...
