SYNTHESIS OF TWO-DIMENSIONAL HYBRID NANOMATERIALS BY MECHANO-CHEMICAL PROCESSING
ES2932474
The presented technology allows the production of 2D hybrid nanomaterials with metal nanoparticles anchored on their surface. The preparation is carried out at room temperature and using ball mills. Drastic conditions and mineral acids are avoided at all stages of the process.
The technology offered provides an efficient method for the preparation of hybrid catalysts of different metals supported on various 2D materials: graphene, boron nitride, molybdenum or tungtan chalcogenides. The necessary mechanochemical treatment allows for mild working conditions, avoids the use of mineral acids, and uses such accessible and sustainable exfoliation agents as glycine or glucose. Lamellar or non-lamellar materials can be used as precursors. Depending on the specific nature of the catalyst (metal + 2D material), they can be applied to different types of chemical reactions, always as heterogeneous catalysts, allowing them to be reused with a simple filtering processes
