Zenyatta Ventures has added Interconnected Reduced Graphene Oxide (IC‐rGO) to its product development pipeline, working with its research partner Prof Aicheng Chen from the University of Guelph, Ontario. IC‐rGO is a three‐dimensional nanomaterial with potential applications in the energy and environmental industries. While working at Lakehead University in late 2016, Chen and his team first developed the nanomaterial using graphite sourced from Zenyatta’s Albany deposit in Northern Ontario – a unique form of graphite ideally suited to produce graphene and graphene derivatives. Patents are pending on the new nanomaterial.
Zenyatta, which changed its management team earlier this year, has announced a new direction as a company, and will focus in the future on exploring new applications for the high‐quality graphene that can be produced from its unique Albany deposit. “Our goal is to become vertically integrated – from producing the graphene right through to the development of high‐value applications for this extraordinary material,” said Dr Francis Dubé, Zenyatta’s Co‐CEO and Head of Business Development and Technology. “We will work with our research partners and other leading industrial partners to become an IP incubator where we will co‐develop IP that has the potential to be a game changer across multiple industries. Dr Chen’s work is representative of the exciting prospects for graphene in years to come.”
“IC‐rGO represents a new class of 3‐D platform, which is promising for many graphene‐related applications such as sensors, catalysts, supercapacitors, batteries, adsorbents, and filters,” said Chen.
The fabricated IC‐rGO exhibits a high capacitance with impressive charging and discharging stability due to its covalent interconnections and unique 3D superstructure. It is anticipated that the discovery could facilitate the research and development of new types of 3D hybrids and functional graphene nanocomposites.

“This invention has the potential to become a structural platform that can be functionalized for multiple applications leading to further innovation and IP for Zenyatta and its shareholders,” said Dubé. “We are very fortunate to have talented research partners like Dr Chen, and we are grateful to him and his team for their world‐leading work in the graphene space.”
Chen and his research group have made significant advances in the development of new graphene‐based nanomaterials from Albany graphite. He and his team have also developed a novel one‐pot synthesis of fluorine functionalized graphene oxide (F‐GO) which was reported in a March 1, 2017 news release. A patent was filed for this invention and a paper describing the process in more detail was published in the Electrochemistry Communications journal.
Zenyatta’s Albany graphite project hosts a large and unique quality deposit of highly crystalline graphite. Independent labs in Japan, UK, Israel, USA and Canada have demonstrated that Zenyatta’s Albany Graphite/Naturally Pure easily converts (exfoliates) to graphene using a variety of simple mechanical and chemical methods. The deposit is located in northern Ontario just 30 km north of the Trans‐Canada Highway, near the communities of Constance Lake First Nation and Hearst. Important nearby infrastructure includes hydro‐power, a natural gas pipeline, a rail line 50 km away and an all‐weather road just 10 km from the deposit.
