报道了采用溶剂热电化学法还原氯仿制备类金刚石碳膜(DLC)的新体系. 实验在－1.2或－1.6 V (vs. Ag/AgCl/Cl－)下, 对溶解在以Bu4NCl作为支持电解质的碳酸丙烯酯(PC)溶液中的氯仿进行电化学还原. 研究了温度、氯仿/PC比例和电极材料对沉积的影响. 采用拉曼光谱, SEM, FTIR, XPS等方法对产物进行表征. 结果表明，在100 ℃，氯仿/PC比例为1∶3, Pt电极上沉积的DLC膜含有较高的sp3杂化态碳. 论文还提出了电化学还原氯仿沉积DLC薄膜的机理.

A new system for deposition of diamond-like carbon (DLC) films through solvothermal electroreduction of chloroform was reported. Chloroform dissolved in a propylene carbonate (PC) solution containing Bu4NCl as supporting electrolyte was electrochemically reduced at low potentials (－1.2 or －1.6 V vs. Ag/AgCl/Cl－). The effect of temperature, volume ratio of chloroform to PC and electrode materials on the deposition were studied. The products were characterized by the Raman spectroscopy, scanning electron microscopy, Fourier-transform infrared spectroscopy, and X-ray photoelectron spectroscopy. A DLC film containing more sp3 hybrid carbon atoms could be deposited at 100 ℃, volume ratio of chloroform to PC of 1/3 on a Pt electrode. The deposition mechanism was discussed.

Key words: diamond-like carbon, solvothermal electrodeposition, chloroform, electroreduction
