岩盐型高熵氧化物(MgCoNiCuZn)O的熔融盐法制备及其葡萄糖传感性能研究
Molten salt preparation of rock-salt structured high-entropy oxide(MgCoNiCuZn)O and its glucose sensing performance
摘要
Abstract
The development of accurate and efficient glucose sensors is crucial for the prevention and management of diabetes.High-entropy oxides offer high thermodynamic stability and strong catalytic activity.Herein,a rock-salt type(MgCoNiCuZn)O high-entropy oxide was designed.The effects of molten-salt method and high-temperature calcination method on the phase structure and sensing performance of the prepared materials were investigated.XRD and SEM showed that the(MgCoNiCuZn)O sample prepared by the molten-salt method possessed higher crystallinity.Its surface morphology consisted of irregular spherical particles with a size of about 1 μm.Electrochemical and glucose sensing tests revealed that the prepared electrode exhibited lower charge transfer resistance and a larger electrochemically active surface area.It demonstrated sensitivities of 246.17 μA·mM-1·cm-2 and 91.73 μA·mM-1·cm-2 in the concentration ranges of 0.02-0.24 mM and 0.24-1.04 mM,respectively.These results indicate that the molten-salt method can effectively reduces the grain size of(MgCoNiCuZn)O and enhances its electrochemical properties.The fabricated sensor exhibits good sensitivity and anti-interference ability.This work provides a new strategy for developing sensing active materials.关键词
