矩形片状介孔NiCo_2O_4催化剂被首次同时用于非酶葡萄糖传感器和非酶葡萄糖燃料电池中.结果表明:在传感器上,介孔NiCo_2O_4催化剂对葡萄糖具有优异的传感特性,如超快的响应时间(小于1 s),超高的灵敏度(662.31μA(mmol L-1)-1cm-2)以及超低的检测限(0.3 nmol L-1at S/N=3);在燃料电池上,介孔Ni Co2O催化剂作为负极材料展示出了良好的应用前景,包括0.63 V的开路电压,0.092 m W cm-24的最大输出功率和1.3 mA cm~-2的极限电流密度.该材料对葡萄糖优异的催化能力归因于介孔结构引起的巨大比表面积能够提供更多的活性位点和NiCo_2O_4本身具有的良好的催化能力.本研究为促进非酶葡萄糖超敏感检测和丰富非酶葡萄糖燃料电池负极催化材料的发展提供了有利的依据.
Rectangular mesoporous NiCo 2 O 4 catalysts were used for the first time in both non-enzymatic glucose sensors and non-enzymatic glucose fuel cells.The results show that mesoporous NiCo 2 O 4 catalysts have excellent sensing properties on glucose such as ultrafast response time (Less than 1 s), ultra-high sensitivity (662.31 μA (mmol L -1) -1 cm -2) and ultra-low detection limit (0.3 nmol L -1at S / N = 3) The Ni Co2O catalyst has good application prospects as a negative electrode material, including an open circuit voltage of 0.63 V, a maximum output power of 0.092 mW cm-24, and a limiting current density of 1.3 mA cm-2. The large specific surface area due to the mesoporous structure can provide more active sites and good catalytic ability of NiCo 2 O 4 itself.In order to promote the non-enzymatic glucose hypersensitivity and enrich the catalytic materials of non-enzymatic glucose fuel cells Provides a good basis for the development of.
