钴铜掺杂煤沥青基多孔炭复合材料的制备及其在传感检测中的应用
Preparation of cobalt-copper doped coal asphalt-based porous carbon hybrid and its application in glucose detection
采用煤沥青为碳源、微米级NaCl为模板剂、过渡金属盐为活化剂和金属源,经共同溶解、高温碳化、水洗,原位形成负载过渡金属氧化物的沥青基多孔炭复合材料。利用XRD、SEM、BET、CV、阻抗、电流-时间响应曲线对材料的结构、形貌和电化学性能进行表征。结果表明,由于双金属组分和多孔炭结构的协同作用,沥青基多孔碳负载CuCo2O4时具有较多的催化活性位点,利于葡萄糖催化氧化反应的进行,其检测限为0.13 μmol/L,线性范围为0.05~0.6 mmol/L,灵敏度为5.76 mA/(mM·cm2),同时具有良好的抗干扰性、选择性和长期稳定性。在人体血清葡萄糖检测中表现出良好的可靠性。
Transition metal oxides-loading coal asphalt-based porous carbon hybrid is in-situ formed through joint dissolution,high-temperature carbonization and water washing processes with coal asphalt as carbon source,water-removable NaCl as template,transition metal salts as activator and metal source.The structure,morphology and electrochemical properties of the hybrid materials are characterized by means of XRD,SEM,CV,impedance and current-time response curves.Results show that due to the synergistic effect of bimetallic components and porous carbon structure,asphalt-based porous carbon supported CuCo2O4 owns larger specific area and more catalytic active sites,which are conducive to the catalytic oxidation of glucose.Under the optimized conditions,a linear dependence is obtained between the glucose concentrations and current response in the range of 0.05-0.6 mM,the detection limit and the sensitivity are 0.13 M and 5.76 mA·mM-1·cm-2,respectively.Moreover,coal asphalt-based porous carbon hybrid also shows acceptable anti-interference,selectivity and long-term stability,suggesting good reliability for the detection of glucose in human serum.
