NEW APPROACH TO PREPARE HIGHLY DISPERSED NON-NOBLE (BI)METALLIC NANOPARTICLES SUPPORTED ON ORDERED MESOPOROUS SILICAS FOR CATALYTIC APPLICATIONS

摘要

Non-noble (bi)metallic supported nanoparticles (NPs) (e.g. Ni, Cu and Co-based) offer a range of technical and commercial advantages, which makes them a feasible alternative to the more expensive supported noble metal NPs (e.g. Pt, Pd, Ir, Au) catalysts. Consequently, over the last decade, an extensive research focused on the preparation methods and/or applications of (bi)metallic supported NPs as catalysts in various (de)hydrogenation processes involved in important fields such as fine chemistry, environmental pollution control, energy and so on. The unique properties of supported NPs are directly related to the specific particle morphology (size and shape), metal dispersion, concentration and the electronic properties of the metal within their host environment.
