报告摘要:

   Mesoporous carbon nitrides (MCN) with large surface areas and uniform pore diameters are unique semiconducting materials and exhibit highly versatile structural and excellent physicochemical properties which find them applications in diverse fields such as metal free catalysis, photocatalytic water splitting, energy storage and conversion, gas adsorption, separation, and even sensing. Although there have been series of mesoporous boron nitride or carbon nitride materials with C3N4 stoichiometry reported [1-6], only a little attention has been given to the mesoporous materials with C3N5, C3N6, C3N7, etc even though they have unique band structure. In this talk, I will present the preparation, structural and morphological control, and the functionalization of highly ordered and graphitic carbon nitride materials with tunable nitrogen contents. The relation between the structural parameters and the performance of these materials in various applications including catalysis, sensing, and carbon capture and energy storage will be demonstrated [7-11]. In the second part of the talk, the fabrication of various nanoporous films including carbons, nitrides, semiconducting nanostructures, and biomolecules with tunable macroporosity, thickness, and morphology will be presented [11]. These porous films have been fabricated by using P123 block copolymer and polystyrene spheres as templates, and utilized for sensing. For example, nanoporous CN film offers the superior affinities for toxic acid molecules but the selectivity can be totally reversed for basic molecule after treatment with UV. The application of these fascinating materials for carbon capture, water splitting, oxygen reduction reaction will also be presented [12-17].

    报告人简介:

    Prof. Vinu is currently working as a Global Innovation Chair Professor and Director of Global Innovative Center for Advanced Nanomaterials at the University of Newcastle. Prior to this, Prof. Vinu was also working as a Full Professor of Nanomaterials, at the Future Industries Institute, University of South Australia, Mawson Lakes, Australia and a Full Professor and ARC Future Fellow at the University of Queensland, Brisbane, Australia during September 2011-2017. Before moving to Australia, he had been working as a senior researcher at the National Institute for Materials Science (NIMS), Tsukuba, Japan since 2006 after he had successfully completed two years of the ICYS fellowship at the same institute and a few years of research at the Technical University of Kaiserslautern (TUK), Germany. Although Prof. Vinu registered his PhD at Anna University, he performed most of his PhD work at the TUK, Germany (2000-2003). During these 20 years of research, Prof. Vinu has made a significant contribution in the field of nanoporous materials and their application in sensing, energy storage, fuel cells, adsorption and separation, and catalysis.

His contribution in the field of nanoporous materials is also clearly reflected by his international ranking by Science Watch as one of the top 15 researchers in the field and has led to ca. 375 papers in high impact factor journals with ca. 17,900 citations and a H-index of 70. His research has been published in top journals like Angew. Chemie, Nano Letters, J. Am. Chem. Soc., Adv. Mater, Adv. Funct., Mater. Chem., Eur. J., Chem. Mater., etc. with an average of 1000 citations per year. At least 45 of his papers have been cited more than 100 times (20 papers have been cited more than 200 times) and 85 papers have been cited more than 50 times. The innovative nature and commercial potential of his research is evidenced by 30 national and international patents.
