Due to its unique properties, graphene is considered to be a strategic material for clean technology industries. According to Zion Market Research, the global graphene market is anticipated to reach US$193.68 million by 2022, growing at a compound annual growth rate of 35.0% between 2017 and 2022. However, there are currently no clean and cost-effective technologies available for the mass production of graphene and graphene derivatives. ZEN Graphene Solutions Ltd. is currently developing its unique igneous-hosted, fluid-derived Albany graphite deposit, which is contained within two large breccia pipes. In January 2018, ZEN announced that it would be focusing its future efforts on value-added graphene converted from Albany graphite in a vertically integrated structure. In light of the many potential graphene applications that ZEN is pursuing, one of the most important requirements for ZEN to achieve commercial success is to develop an environmentally compatible, low-cost, and facile exfoliation technique. The objectives of this NSERC CRD project are three-fold: (i) to effectively electrochemically exfoliate the Albany graphite to produce graphene and graphene-based nanomaterials; (ii) to efficiently produce graphene quantum dots (GQDs) with a high yield and good quality; and (iii) to characterize the fabricated graphene, graphene-based nanomaterials, and GQDs, while exploring their environmental and energy applications. ZEN recently completed a large diameter RCD drill program at the Albany Graphite Deposit resulted in the extraction of a 110-tonne bulk sample of graphite-mineralized material from the East Pipe. The company anticipates the production of up to six tonnes of high-quality graphene precursor material from this program. ZEN foresees using the results of this proposed NSERC CRD research to develop a scalable commercial exfoliation technique that will enable the conversion of significant quantities of Albany graphite to graphene-based nanomaterials. Commercial success in this regard would launch the full mining operation of the Albany Deposit, toward the creation of many highly sought after professionally skilled jobs for the Northeastern Ontario economy.

由于其独特的性质，石墨烯被认为是清洁技术行业的战略材料。根据锡安市场研究公司的数据，到2022年，全球石墨烯市场预计将达到1.9368亿美元，2017至2022年间的复合年增长率为35.0%。然而，目前还没有清洁且具有成本效益的技术可用于大规模生产石墨烯和石墨烯衍生物。Zen Graphene Solutions Ltd.目前正在开发其独特的火成岩赋存、流体来源的奥尔巴尼石墨矿床，该矿床包含在两个大型角砾岩管道中。2018年1月，Zen宣布，未来将专注于从奥尔巴尼石墨转化为垂直一体化结构的附加值石墨烯。鉴于Zen正在追求的许多潜在的石墨烯应用，Zen要取得商业成功，最重要的要求之一是开发一种环境友好、低成本和简便的剥离技术。NSERC CRD项目的目标有三个：(I)有效地电化学剥离Albany石墨以制备石墨烯和石墨烯基纳米材料；(Ii)高效地高产率和高质量地制备石墨烯量子点(GQD)；(Iii)表征所制备的石墨烯、石墨烯基纳米材料和GQD，并探索其在环境和能源方面的应用。Zen最近在Albany石墨矿床完成了一个大直径RCD钻探项目，从EAST管道中提取了110吨的大量石墨矿化材料样品。该公司预计该项目将生产高达6吨的高质量石墨烯前体材料。Zen预计，利用这项拟议的NSERC CRD研究结果，开发一种可扩展的商业剥离技术，使大量奥尔巴尼石墨能够转化为基于石墨烯的纳米材料。在这方面的商业成功将启动奥尔巴尼矿藏的全面采矿作业，为安大略省东北部的经济创造许多备受欢迎的专业技能工作。
