Abstract

Although enormous scientific progress has been made in the application of graphene and its related materials, the cost-effective and scalable production of graphene still holds the key to its commercialization. Ease of graphene production is especially important if it is to be used in bulk applications (e.g. energy storage in automobiles) where the large scale and low cost production of the active materials is required. This talk will cover three promising, scalable methods of graphene production, namely the graphite oxide, liquid-phase exfoliation (LPE) and electrochemical routes, with focus on their recent progress and remaining challenges. In particular, emphasis will be placed on the electrochemical methods as they preclude the use of chemical oxidants as the driving force for intercalation or exfoliation, and such an electromotive force is controllable for tunable GICs. More importantly, the extensive capabilities of electrochemical functionalization and modification enable the facile synthesis of functional graphene and its value-added nanohybrids.

Biography

Since May 2016, Dr Zhong is an Australia Research Council DECRA Research Fellow and Senior Lecturer at Griffith University, Centre for Clean Enivornment and Energy, at Gold Coast Campus. He completed his Ph.D. in Chemistry at the National University of Singapore under Prof Kian Ping Loh and had worked on the surface engineering of nanocrystalline diamond for biosensing, photovoltaics and molecular electronics applications. During his postdoctoral training at Princeton University (with Prof Steven Bernasek) and MIT (with Prof Timothy Swager), he discovered the use of ultrasound to be a mild and effective method for conjugation of photo-sensitive molecules on silicon surface and achieved breakthrough in enhancing the electrochemical expansion of graphite. After spending three years at USA, he returned to Singapore to worked as a Research Scientist at Institute of Bioengineering and Nanotechnology, A-STAR, and had expanded his research interest to encompass nanocomposite materials for bio and energy-related applications. Prior to his continuing position at Griffith University, he was a ARC DECRA Research Fellow at Monash University, Department of Materials Science and Engineering, for about two and half years.
