摘要
由于铋的毒性小,在电化学分析中的电位窗口宽,氢的过电位高以及易与金属形成合金等优点,被作为汞的替代材料广泛应用到电化学环境分析检测中。我们通过模板法、电化学还原法、水热法以及化学还原法制备了还原氧化石墨烯负载的铋纳米颗粒、铋纳米球、铋纳米片、多孔铋和铋微纳米棒等不同形貌的铋基材料。这些新型材料作为电极修饰材料在电化学检测中有很好的效果,已成功应用到海岸带水体金属离子的检测中。
Bismuth material has been extensively studied in the electrochemical analysis instead of mercury for its environmental friendliness, a wide potential window, high overpotential of hydrogen and the ability to form alloys with many metals. Herein, different morphologies of bismuth-based materials such as reduced graphene oxide-bismuth nanoparticles, bismuth nanospheres, bismuth nanosheets, porous bismuth and bismuth microrods have been synthesized through template method, electrochemical reduction method, hydrothermal reduction method and chemical reduction method. Those novel bismuth-based materials were excellent used in electrochemical analysis and were successfully applied to the determination of metals in real coastal waters.
