Synthetic architecture of nanomaterials:  In recent years, synthesis of zero-, one-, two- and three-dimensional (0D, 1D, 2D and 3D) materials has become a focal area in nanostructured materials research, owing to their many low dimensional characteristics different from the bulk properties. To constitute a complete toolbox for the "bottom-up" approach in nanotechnology, the ability of making functional materials into various artificial nanokits and nanoparts is essential. Nanostructured materials can be prepared with constrained or unconstrained synthetic methods, in which inorganic or organic templates (e.g., porous oxides, well-oriented crystal planes, organic ligands, solution inhomogeneity, and supramolecular arrays) have been utilized. In addition to the template-assisted methods, a number of template-free approaches (such as Ostwald ripening and Kirkendall effect for solid evacuation in forming hollow nanostructures) have also been developed. Our research is focused on development of novel synthesis methods for complex and composite nanobuilding blocks and their related self-assemblies. In analogy to total synthesis of organic compounds, complex inorganic nanostructures with aesthetic expression can be prepared in solution media via synthetic architecture, in which fabrication of building components and their organizations may take place simultaneously or consecutively. In particular, large-scale synthesis and organization of light-absorbing semiconducting nanostructures in a control manner have formed a main part of the research program. Applications of these nanomaterials are directed to chemical sensing, heterogeneous catalysis, energy storage, solar-cells, and medical diagnosis etc in many advanced technologies.

 

Self-assembly for complex nanostructures:  One of the major technological challenges in nanoscience and nanotechnology is the self-assembly of tiny nano-building units (nanokits and nanoparts) into larger organized conformations and geometrical architectures for device applications.  Nonetheless, most of morphological organizations of nanomaterials to-date are mainly focused on organic surfactant assisted self-assembly at low or moderate temperatures.  To make organized nanomaterials usable in high-temperature environments (e.g., heterogeneous catalysis and laboratory-on-a-chip applications), large-scale organization of inorganic (such as metals and metal oxides) nanostructures in a control manner at elevated temperatures is highly desirable.  We had recently adventured into this emerging field; our research is concentrated on the exploration of various novel organization schemes such as "oriented attachment", growth-cum-assembly processes, lattice-strain-induced organization, space-predefined assembly, tiered architectures at multiple length scales, and in-situ generation of surface capping for self-assembly under “one-pot” or “multi-pot” conditions, including design and integration of inorganic-organic nanohybrids.

 

Integrated nanocatalysts:  The classic heterogeneous catalysts consist of active nanoscale metal components and solid carriers, namely “inert” oxide supports such as alumina, silicates, or magnesium oxide, to increase reaction surface area and metal utilization. However, in many cases, traditional catalyst technology still remains more of an art than a science. In contrast, monodisperse metallic nanoparticles, for example 1 to 4 nm in size, can be presynthesized in solution media and later assembled evenly onto catalyst supports at relatively low temperatures. It should be mentioned that one of unique features of the self-assembled catalysts is that original active sites of the oxide support can be well preserved, as there are plenty of unanchored areas of oxide supports in the resultant catalysts. Apart from the loaded active metal nanoparticles, metal-free areas of oxide carriers can be attained facilely with the self-assembly approach. These metal-free areas preserve intrinsic chemical functionality of the supporting materials, assuring the genuine composite nature and synergistic effect of a materials system if desired. Another fabrication strategy for complex nanostructured catalysts in our recent investigations is “synthetic architecture”, in which fabrication and organization of individual components may take place simultaneously or consecutively. With careful selection of shell texture and thus porosity, furthermore, membrane reactor like complex nanocomposites can be prepared, with which an extra functionality in separation can be further attained. Therefore, we are currently pursuing exploratory research in this technologically important area – development of state-of-the-art heterogeneous catalysts via integrative approaches.
