摘　　要：本文采用水热法,利用不同比例的镍钴铬3种金属制备三元水滑石材料,并分析其结构性能特点。利用扫描电镜对镍钴铬三元水滑石(NiCoCr-LDH)的表面形貌进行表征,用X射线衍射仪对水滑石的晶形特点进行了表征,用红外光谱对水滑石的层间官能团进行分析。把材料修饰在玻碳电极(GCE)表面,利用电流-时间法探讨了NiCoCrLDH/GCE的电催化活性。在碱性条件下NiCoCr-LDH材料具有催化活性,能够氧化葡萄糖。In this paper, three kinds of ternary hydrotalcite materials were prepared by hydrothermal method using different proportions of nickel, cobalt and chromium precursor, and their structural properties were analyzed. The surface morphology of NiCoCr-LDH was characterized by scanning electron microscopy （SEM）. The crystal properties of hydrotalcite were detected by X-ray diffraction （XRD）. The functional groups of hydrotalcite were analyzed by infrared spectroscopy. Moreover, the electrocatalytic activity of NiCoCr-LDH / GCE was investigated by current-time method, which showed NiCoCr-LDH materials could oxidize glucose under alkaline conditions.
