Abstract
Colloidal nanocrystals (NCs) are solution-grown, nanometer-sized, inorganic particles that are stabilized by a self-assembled monolayer (SAM) of surfactants attached to their surface. NCs possess useful properties that are controlled by their composition, size and shape, and the SAM coating ensures that these structures are easy to fabricate and process further into more complex structures. This combination of features makes colloidal NCs attractive and promising building blocks for advanced materials, green chemistry, and specifically in catalysis. Colloidal NCs are potentially able to blend the many advantages of heterogeneous catalysis with the versatility of homogeneous catalysts. This presentation will focus on: i) Advantages of continuous-flow processing in in-situ preparation of Fe3O4 NCs from a Fe (e.g., FeCl2•4H2O, FeCl3•6H2O, and Fe(OAc)2) precursor using hydrazine hydrate as the reducing agent to catalyze the organic reactions (e.g., reduction of nitroarenes). ii) Shape-selective synthesis TiO2 colloidal NCs and their application in a continuous-flow photocatalytic transformation.
