Advancement in development of nanomaterials relies on the capability of altering their properties at the nanoscale.  In such effort, the approach that considers well-defined systems is of great importance.  The knowledge obtained from bulk materials is utilized to tailor nanoscale properties of the materials that are relevant for energy conversion and storage.  It has been demonstrated that employment of multimetallic systems could offer unprecedented benefits in functional properties of materials.  The reported synergy between well-defined systems and corresponding and nanoparticles emphasizes an efficient approach in design and synthesis of advanced nanomaterials.Such research effort involves the following steps:  1) characterization of well-defined solid materials by varying their surface structure, composition profile and electronic properties [1];  2) atomic/molecular level characterization of electrified solid-liquid interfaces [2];  3) theoretical modeling of structure/function relationship;  4) identification of the most active and stable sites at atomic scale during reaction conditions;  5) bond-making and bond-breaking processes at the electrochemical interfaces;  6) modification of the surface and subsurface composition by other constituents aimed to improving functionality [3];  7) synthesis of advanced (nano)materials with tailored structures.Novel nanoscale structures show substantial improvement of their functional properties under the real conditions.References:[1]  Stamenkovic et al.
