英文摘要 | The performance criteria for the design of all-solid-state ion-selective electrodes mainly include high electrode-to-electrode reproducibilityand a low potential drift. Here, we introduce nickel cobalt sulfide (NiCo2S4)as a solid contact for ion-to-electron transduction based on multiple redoxcouples. NiCo2S4materials with different morphologies can be preparedthrough a facile hydrothermal/solvothermal method. A NiCo2S4-based solid-contact Ca2+-ISE has been developed, which exhibits a Nernstian slope of27.5 +/- 0.2 mV/dec in the activity range from 1.0x10-6to 2.9x10-2Mwith a detection limit of 5.0x10-7M. A variation of the standard potentialE degrees for eight individual solid-contact electrodes can be obtained as low as 0.35mV. Due to the synergistic effect of cobalt and nickel ions in the ternarysulfide, an excellent redox capacitance (565 mu F) of the buried solid contactcoated with the ion-selective membrane can be achieved and is much largerthan those obtained from other redox solid-contact materials reported so far, thus yielding a high potential stability of 2.2 +/- 0.4 mu V/h. In addition, the NiCo2S4-based solid-contact Ca2+-ISE shows a reduced water layer at the sensing membrane/NiCo2S4interfaceand provides an excellent resistance to the interferences from light, O2, and CO2. The proposed strategy utilizing NiCo2S4as a solidcontact is a promising alternative for the fabrication of calibration-free ASS-ISEs. |
