据报道，一种简单、绿色、经济的方法通过电化学剥离水溶液中的铅笔芯来合成高质量的氧化石墨烯（GO）薄片。氧化石墨烯薄片在碱性溶液中表现出良好的电催化活性和耐氧性。我们目前的研究结果有望以低成本和环保的方式大规模制备氧化石墨烯并进一步商业化。
A simple, green and cost-effective approach has been reported to synthesize high-quality graphene oxide (GO) flakes via electrochemical exfoliation of pencil cores in aqueous electrolytes. The exfoliated GO flakes exhibit excellent electrocatalytic activity and toxicity tolerance for oxygen reduction reactions in alkaline solution. Our present results are promising for scaled-up preparation and further commercialization of graphene oxide in a low-cost and environmentally friendly way.
