Mesoporous materials have been receiving a lot of attention owing to their excellent textural parameters including high specific surface area, large pore volume and uniform pore size distribution. These properties make them available for various applications including energy storage and conversion, adsorption, separation, catalysis, sensing and drug delivery. By modifying the functional elements in the framework structure of the mesoporous materials, the application possibilities of these materials could easily be expanded. For example, the incorporation of hetero atoms such as boron and nitrogen in these mesoporous materials can introduce new properties to these materials including electronic and semi-conducting properties. Although there have been series of mesoporous boron nitride or carbon nitride materials with C3N4 stoichiometry reported，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. 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. 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.
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.
The quality of his research has been recognised with several international awards including Medal, Chemical Research Society of India 2018, SPARC award 2019, CNR Rao Lectureship award 2019. Medal and KY NIEM CHUONG Award 2018, Scopus Young Researcher Award 2014, Friedrich Wilhelm Bessel award by the Humboldt Society (2010), JSPS Senior Invitational Fellow for the year 2014, Australian Future Fellowship (Professorial Level) for the year 2010, Indian Society for Chemists and Biologists award for excellence for the year 2010, Catalysis Society of India Young Scientist award for the year 2010, Chemical Society of Japan Award for the Young Scientist for the year 2008, Laureate of Khwarizmi International Award 2008, Asian Excellent Lectureship Award, and ICYS fellowship. Prof. Vinu is honoured with the Fellow of Royal Society of Chemistry, FRSC (UK), Fellow of Royal Australian Chemical Institute (FRACI), Fellow of World Academy of Ceramics (FWAC), Fellow of World Academy of Art and Science (FWAAS), Fellow of Asia-pacific Academy of Materials (FAPAM) and Foreign Fellow of Maharashtra Academy of Sciences, FFMAS.
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. 380 papers in high impact factor journals with ca. 18,300 citations and a H-index of 72. 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.
He has also been invited to write several chapters by renowned publishers including Wiley, Elsevier and American Scientific. He is the Editor of Science of Advanced Materials and Australian Editor of Journal of Nanoscience and Nanotechnology. Professor Vinu is in the Editorial board of several journals namely Materials Today Nano, Emergent Materials, Scientific Reports, Chemical Record, Journal of Nano Science and Nanotechnology, Current Science, etc. He has been invited to deliver presentations at numerous international conferences, workshops and seminars and chaired sessions of several international conferences. Prof. Vinu has visited institutes in more than 40 countries to deliver lectures and gave ca. 215 lectures including 33 plenary and 28 keynote lectures at international conferences as well as ca. 165 invited talks. He was also offered honorary professor position from leading universities including Hokkaido University, Japan, Yonsei University, South Korea, Kyungpook National University, South Korea, Fudan University, China, Jilin University, China, Mangalore University, India, and Anna University, India, and Adjunct Principal Researcher from Korean Research Institute for Chemical technology, Daejeon, South Korea.
