石墨烯异质结构修饰玻碳电极对邻苯二酚的灵敏检测OA北大核心
Graphene-based Heterostructure Modified Glassy Carbon Electrode for Sensitive Detection of Catechol
邻苯二酚(CC)是高毒性的酚类污染物,对其灵敏检测对于环境监测具有重要意义.本研究以石墨烯(GR)为模板制备了石墨炔/石墨烯(GDY/GR)异质材料,作为检测CC的高性能电化学传感材料.GR在GDY生长过程中具有外延模板的作用.电化学实验结果表明,GDY/GR修饰的玻碳电极(GCE)对CC表现出优异的电化学响应,线性范围为1～900 μmol/L,检出限低至0.11 μmol/L.同时,GDY/GR/GCE还具有良好的抗干扰能力、稳定性和重复性.将GDY/GR/GCE用于实际水样中CC的检测,检测结果与高效液相色谱法测定结果一致,表明本方法在环境监测方面具有良好的实际应用潜力.
Catechol(CC)is a highly toxic phenolic pollutant,and its sensitive detection holds significant importance for environmental monitoring.Herein,graphene was used as a template to prepare graphdiyne/graphene(GDY/GR)heterogeneous materials,serving as high-performance electrochemical sensing materials for CC determination.GR played the role of an epitaxial template during the growth of GDY.The electrochemical experiment results demonstrated that the glassy carbon electrode(GCE)modified with GDY/GR showed excellent electrochemical response to CC,with a wide linear detection range(1-900 μmol/L)and a low detection limit(0.11 μmol/L).Meanwhile,GDY/GR/GCE also exhibited good anti-interference ability,stability and reproducibility.More importantly,the practicality of GDY/GR/GCE was evaluated and satisfactory results were obtained in actual water samples,which showed significant potential for practical applications in environmental monitoring.
