Abstract

The porous cobaltosic oxide (Co3O4) arrays has been prepared by a chemical co-precipitation route using the nickel foam as s substrate. Cyclic voltammetry (CV), and ampere current method (i-t curve) are used to explore the non-enzymatic glucose sensor in a three-electrode system. This porous Co3O4 array non-enzymatic sensor shows a sensitivity of 592.8 mA mM1 cm2 in concentration from 0.99 M to 1.073 mM. The porous Co3O4 array sensor electrode also showed low LOD value (0.005 M) and fast response time (4 s). This porous Co3O4 electrode shows a good sensor performance due to these rich redox reaction sites in the unique porous structure. This porous cobaltosic oxide arrays maybe a potential sensor material in the glucose detection application

共沉淀法制备多孔Co3O4阵列及其在非酶葡萄糖传感器中的应用

以泡沫镍为衬底，采用化学共沉淀法制备了多孔氧化钴(Co3O4)阵列。采用循环伏安法(CV)和安培电流法(i-t曲线)对三电极系统中的非酶葡萄糖传感器进行了研究。该多孔Co3O4阵列非酶传感器在浓度范围为0.99M ~ 1.073 mM范围内的灵敏度为592.8 mA mM (1 cm) mg (1 cm) mg(2)，且具有较低的LOD值(0.005M)和快速的响应时间(4 s)。该多孔Co3O4电极独特的多孔结构中含有丰富的氧化还原反应位点，具有良好的传感器性能。这种多孔氧化钴阵列可能是葡萄糖检测中潜在的传感器材料
