One-step synthesis of the nanocomposite of few-layer graphene structures with cobalt oxides was realized using the method of electrochemical exfoliation of graphite. The exfoliation process was carried out in alternating anodic-cathodic plasma mode in 1 M Na₂SO₄ + 0.01 M CoSO₄ solution. Obtained nanocomposite was characterized by scanning and transmission electron microscopy, X-ray photoelectron and Raman spectroscopy. Besides, a catalytic activity of the nanocomposite of few-layer graphene structures with cobalt oxides towards the oxygen reduction reaction was assessed, and a considerable decrease in the oxygen reduction overpotential and an electron transfer number of ca. 3.6 were demonstrated. The observed effect was found to be caused by 40 wt% of cobalt (II) and (III) oxides in the nanocomposite.

利用石墨的电化学剥落方法，实现了氧化钴对一层石墨烯结构纳米复合材料的一步合成。剥离过程是在1M Na ₂ SO ₄  + 0.01 M CoSO _4中以交替的阳极-阴极等离子模式进行的解。通过扫描和透射电子显微镜，X射线光电子和拉曼光谱对获得的纳米复合材料进行表征。此外，评估了具有氧化钴的几层石墨烯结构的纳米复合材料的纳米复合材料对氧还原反应的催化活性，并且氧还原超电势的显着降低和电子传递数约为ca。3.6进行了演示。发现观察到的效果是由纳米复合物中40重量％的钴（II）和（III）氧化物引起的。
