Abstract
A comparative study has been conducted on the cathode electrolysis plasma emission spectra recorded during the plasma-assisted electrochemical exfoliation of black phosphorus and graphite under maximally identical experimental conditions. It has been found that in the case of black phosphorus exfoliation, the concentration of active intermediates (OH radicals and O atoms) in electrolytic plasma is significantly lower than that in the case of the graphite electrode. It has been assumed that this effect is due to the fact that the rate of interaction of the above intermediates with the synthesized phosphorene structures is significantly higher than the rate of interaction with graphene-like particles. This assumption has been confirmed by the detection of a significantly higher oxygen content in the exfoliation products of black phosphorus than the oxygen content in the synthesized carbon nanoparticles.
摘要 在最大程度相同的实验条件下，对黑磷和石墨在等离子体辅助电化学剥离过程中记录的阴极电解等离子体发射光谱进行了比较研究。研究发现，在黑磷剥离的情况下，电解等离子体中活性中间产物（OH 自由基和 O 原子）的浓度明显低于石墨电极。据推测，产生这种效应的原因是上述中间产物与合成磷烯结构的相互作用速率明显高于与类石墨烯颗粒的相互作用速率。通过检测黑磷剥离产物中的氧含量明显高于合成碳纳米颗粒中的氧含量，证实了这一假设。
