摘要

以类沸石咪唑酯骨架结构材料Co(bIm)₂(ZIF-9)为前躯体,在氮气氛围中进行700℃热解,得到了掺杂氮的多孔碳材料Co/C-700。利用原位掺杂,同时高温碳化ZIF-9和硫粉,在同样条件下合成氮-硫双掺杂的多孔碳材料CoS/C-700。对合成材料Co/C-700和CoS/C-700进行了表征,显示了样品的成功合成。同时研究了Co/C-700和CoS/C-700作为修饰碳糊电极材料在碱性电解液中的电化学性质,Co/C-700和CoS/C-700具备良好的电化学可逆性,可作为电极材料。

Abstract

Zeolite imidazole ester frame structure material Co(bIm)₂(ZIF-9) was used as sacrifice template for the direct synthesis of porous carbon material Co/C-700 by 700℃ pyrolysis in N₂.Nitrogen and sulfur dual-doped porous carbon material CoS/C-700 was synthesized using in-situ formation in mentioned above reaction condition.Samples were characterized,and the results illustrated the successful synthesis.The electrochemical property of Co/C-700 and CoS/C-700 as modified CPE materials was researched in alkaline electrolyte.The results showed that Co/C-700 and CoS/C-700 had good electrochemical reversibility and could be the electrode material.
