Abstract

Although enormous scientific progress has been madein the application of graphene and its related materials, the cost-effectiveand scalable production of graphene still holds the key to itscommercialization. Ease of graphene production is especially important if it isto be used in bulk applications (e.g. energy storage in automobiles) where thelarge scale and low cost production of the active materials is required. Thistalk 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 useof chemical oxidants as the driving force for intercalation or exfoliation, andsuch an electromotive force is controllable for tunable GICs. More importantly,the extensive capabilities of electrochemical functionalization andmodification enable the facile synthesis of functional graphene and itsvalue-added nanohybrids.

Biography

Since May 2016, Dr Zhong is an Australia Research Council DECRAResearch Fellow and Senior Lecturer at Griffith University, Centre for CleanEnivornment and Energy, at Gold Coast Campus. He completed his Ph.D. inChemistry at the National University of Singapore under Prof Kian Ping Loh andhad worked on the surface engineering of nanocrystalline diamond forbiosensing, photovoltaics and molecular electronics applications. During hispostdoctoral training at Princeton University (with Prof Steven Bernasek) andMIT (with Prof Timothy Swager), he discovered the use of ultrasound to be amild and effective method for conjugation of photo-sensitive molecules onsilicon surface and achieved breakthrough in enhancing the electrochemicalexpansion of graphite. After spending three years at USA, he returned toSingapore to worked as a Research Scientist at Institute of Bioengineering andNanotechnology, A-STAR, and had expanded his research interest to encompassnanocomposite materials for bio and energy-related applications. Prior to hiscontinuing position at Griffith University, he was a ARC DECRA Research Fellowat Monash University, Department of Materials Science and Engineering, forabout two and half years.
