Abstract

The electrochemical reactions of carboxylic and lactone groups on carbon nano-onions (CNOs) in aqueous solutions result in non-Kolbe products: alcohols, ketones, ethers and epoxides. The anodic/cathodic conversion of ox-CNOs was assessed by Boehm titrations and by Raman and DRIFTS-FTIR (diffuse reflectance infrared Fourier transform spectroscopy). The electrochemical properties of oxidized carbon nano-onions were investigated by cyclic voltammetry in aqueous solutions. The ox-CNOs are electrochemically active as a result of the reduction of the oxygen-containing groups.

摘要

碳纳米洋葱（CNO）上羧酸和内酯基团在水溶液中的电化学反应产生非科尔贝产物：醇、酮、醚和环氧化物。通过 Boehm 滴定、拉曼和 DRIFTS-FTIR（漫反射红外傅里叶变换光谱）评估了 ox-CNO 的阳极/阴极转化。通过在水溶液中的循环伏安法研究了氧化碳纳米洋葱的电化学性质。由于含氧基团的还原，ox-CNO 具有电化学活性。
