Seminar: Nanoscale Assembly of 1D/2D Materials for Energy and Environmental Applications

Abstract: Rational design of 1D/2D materials is crucial for the realisation of their profound implications in energy and environmental fields. The past decade has witnessed a significant development in 1D/2D materials research, yet a number of critical challenges still remain for real-world applications. Nanoscale assembly, precise control over the orientational/positional ordering and complex interface among various dimensional materials, is essential for continued progress of nanomaterials especially for energy storage/conversion and environmental remediation. This talk highlights the dimensional microstructures of nanomaterials for energy and catalytic applications, especially for photo/electro-catalysts, lithium ion batteries, and supercapacitors, with a particular emphasis on the nanoscale organisation. First, geometric dimensional diversity of nanomaterial assembly will be focused based on the novel assembly mechanisms, including 1D fiber from colloidal liquid crystalline phase, 2D film by interfacial tension and 3D nanoarchitecture assembly by electrochemical processes. Second, interesting hierarchical nanostructures with various functional materials, including (i) polymers, (ii) transition metals, and (iii) metal oxides, nitrides, sulfides will be introduced.
