无酶过氧化氢电化学传感器材料的研究进展

摘要

Different kinds of electrode materials for the non-enzymatic hydrogen peroxide electrochemical sen⁃sors were focused, mainly including nobel metal nanomaterials(Pt and Ag), transition metal and its oxide nano⁃materials(Cu, Mn and Co), alloy-based nanomaterials, carbon nanotubes, grapheme and graphene oxide-based nanomaterials. The performances(such as test potential, sensibility, linear range, selectivity)of the non-enzy⁃matic hydrogen peroxide electrochemical sensors were analyzed. The applications of the above electrode materi⁃als in non-enzymatic hydrogen peroxide electrochemical sensors in recent five years were discussed and their characteristics were included. The detection principles of the various sensors were analyzed and some sugges⁃tions for the further development of non-enzymatic hydrogen peroxide electrochemical sensors were given. It indi⁃cated that the nanomaterials with larger surface area and special morphologies are the key for improving the detection performance of the non-enzymatic hydrogen peroxide electrochemical sensors. Meanwhile, the possible commercial application of non-enzymatic hydrogen peroxide electrochemical sensors was forecasted.%综述了当前无酶过氧化氢电化学传感器的研究进展，重点介绍了各种无酶过氧化氢电化学传感器所使用的电极材料，主要包括：铂、银等贵金属纳米材料；铜、锰、钴及其氧化物等过渡金属纳米材料；各类合金基纳米材料；碳纳米管、石墨烯、氧化石墨烯等碳基纳米材料。分析了各类材料所构建的无酶过氧化氢电化学传感器检测性能，如测试电位、灵敏度、检测限、选择性等，总结了近5年来各类新型材料在此类传感器上的应用和各自特点，分析了各类传感器的检测原理，对这类传感器的进一步发展提出了相应的建议，指出发展具有更大比表面积、形貌特殊的纳米及其复合材料是提高检测性能的重要方向，同时，也对无酶过氧化氢传感器在商业化上应用可能性进行了展望。
