Canadian graphite powder supplier Zenyatta Ventures Ltd says that a team of scientists under the direction of Dr Aicheng Chen at Lakehead University, Ontario, Canada, has made significant advancements related to sensing application development with the first graphene oxide (GO) invention produced from the company’s high-purity Albany graphite.
Dr Chen and his team have developed a one-pot synthesis of fluorine functionalized graphene oxide (F-GO) which can be used in many energy, environmental and electrochemical sensing applications. The produced F-GO has been tested for the simultaneous detection of various toxic metal ions (e.g. mercury, lead, cadmium and copper) and a substantial improvement in the electrochemical sensing performance was achieved in comparison with GO. A patent has been filed by Dr. Chen for this invention and a paper describing the process in more detail was recently published in the latest volume of Electrochemistry Communications.
‘We found Zenyatta’s high-purity Albany graphite to be an ideal material for the production of graphene oxide and subsequent application development,’ said Dr Chen. ‘Interestingly, it appears that the distinct particle size and morphology of Albany graphite are important factors in the ease of production of high-quality graphene and GO.’
