      In the ‘bottom-up’ approach of the synthesis of nanomaterials, rationally designed molecular precursors, which have particular sets of properties, are transferred into nanoscaled and nanostructured materials by so-called ‘soft-chemistry methods’ such as MOCVD in the gas phase and sol-gel and MOD in the liquid phase. In majority of the cases, the inherent structural units of the precursor molecules are retained in the nanomaterials. This presentation will emphasize the importance of mastering the precursor chemistry as it allows one to control the chemical and structural characteristics of the produced nanomaterials. The main advantages of this approach are low processing tem­pe­ra­tu­res, low or­ga­nic con­ta­mi­na­ti­on, and higher quality of the materials. The factors governing the divergent reactivity and the structures of the precursors will be discussed.Catalytic applications of these nanocrystals, either as support for gold calalysts in the oxidation reactions or their nanocomposites with titania for photocatalysis will be discussed. A section of this presentation will also be devoted to the judiciously engineered inorganic-organic hybrid complexes based on metal-organic cations and iodometallate anions which show interesting structural features & new properties by the synergic effects of two or more metals.

     Shashank Mishra is Associate Professor of Chemistry at the Claude Bernard University of Lyon 1 (UCBL), France. He obtained his Ph.D. degree (2002) under the supervision of Prof. Anirudh Singh, at the University of Rajasthan, Jaipur (India), and, subsequently, served as a lecturer (2002−2004) at Bundelkhand University (India). In 2004, he was selected for the French CNRS postdoctoral fellowship to work on the molecular precursors for high-tech materials with Prof. Liliane G. Hubert-Pfalzgraf at the Institut de recherches sur la catalyse (now IRCELYON). Later, he was associated with Prof. Stéphane Daniele (2007−2010) and Prof. Christophe Dujardin (2010−2011) at the IRCELYON and Laboratoire de Physico-Chimie des Matériaux Luminescents (now Institut Lumière Matière), respectively, before being appointed as a faculty at UCBL in September of 2011. His present research interests are concerned with the design of molecular precursors of oxide and non-oxide materials and understanding their transformations via solutions or vapor phase routes for different applications.
