摘要：

In comparison to the classical liquid-contact ion-selective electrode (LC-ISE), the potential stability remains one of the major challenges currently faced by the solid-contact ion-selective electrode (SC-ISE). This challenge can be addressed by introducing a conducting layer between the conductive substrate and the polymer membrane to stabilize the potential output. In this paper, hollow carbon nanospheres loaded with zinc cobaltate nanoparticles (ZnCo 2 O 4 @HCNs) were synthesized by using a one-pot method, which served as an ion-electron con...
