报告人简介：

Jian Liu joined the Department of Chemical Engineering of the Curtin University in April 2013 as a Lecturer. Supervised by Prof. Qihua Yang and Prof. Can Li, he obtained his Ph.D. degrees in Physical Chemistry from the Dalian Institute of Chemical Physics, Chinese Academy of Science, China, in 2008. He then joined Australian Institute for Bioengineering and Nanotechnology (AIBN), The University of Queensland (UQ) as a research fellow. A recent search of ISI Web of Science shows his entire publications have been cited for over 1800 times. He has an H-index of 25 and his research has been featured on 9 Cover pages of scientific journals. As recognition of his achievements in research, he was honoured with a prestigious UQ Foundation Research Excellence Award, Australian Postdoctoral Fellowship (APD), UQ Postdoctoral Research Fellowship, President Award (Chinese Academy of Sciences) and a Young Scientists Award of the 14th International Congress on Catalysis. His current research interests include colloidal nanoporous carbon spheres for Li-S battery, yolk shell nanostructured materials as delivery vehicles and nanoreactors. 

报告摘要：

Nano/mesoporous materials have attracted growing interests owing to their special properties, including uniform nanopores and a high specific surface area. We have focused on fine controls of compositions, morphologies, functionalities which are important factors for design of porous materials with new functionalities. In this presentation, I will discuss our recent works on morphological control synthesis of nanoporous materials including mesoporous hollow spheres, mesoporous yolk shell nanoparticles, and monodispersed microporous and mesoporous carbon spheres. (i) Specifically, we have synthesized multi-shelled mesoporous silica hollow nanospheres (MMSHNs) with uniform size distribution (~150 nm), tuneable shell thickness (7-20 nm) and layer number (1-4 layers) through a facile vesicle template approach. These hollow nanospheres demonstrated a good selective adsorption capacity for Methylene Blue dye. (ii) We also synthesized yolk/shell or ‘rattle-typed’ nanomaterials (YSNs) with nanoparticle cores inside hollow shells, which are interesting among the complex hollow nanostructures due to their tailorability and functionality in both the cores and hollow shells. We have developed some strategies for the synthesis of YSNs with controllable sizes, compositions, geometries, structures and functionalities. Applications of these new materials in a wide range of potential areas are conducted including nanoreactors, biomedicine and lithium-ion batteries. (iii) I will also demonstrate the concept for carbon nanostructured electrode materials, including novel mesoporous carbon nanoparticles, core shell and yolk shell carbon nanoparticles with hierarchical porous structures. By using these nanostructured materials as electrodes, a new generation of supercapacitors to complement or replace batteries in certain applications where high efficiency, high power, and high level of reliability will be developed. For example, we recently developed a strategy to synthesize monodisperse polymer spheres from resorcinol–formaldehyde (RF) resin and carbon “St？ber” spheres. This method allows for excellent control of the particle size ranging from 200 to 1000 nm. Monodisperse carbon spheres can be produced with high yield and tunable size between 150 and 900 nm by carbonisation.
