Enhanced electrochemical Cs <sup>+</sup> extraction performance enabled by a MoS <sub>2</sub> /Ni <sub>3</sub> S <sub>2</sub> heterostructure counter electrode
In this work, for the first time, an MoS<sub>2</sub>/Ni<sub>3</sub>S<sub>2</sub> heterostructure (MSNS) was employed as the counter electrode. When combined with an unmodified Cu-PBA working electrode, the equilibrium adsorption capacity reached up to 579.66 mg g<sup>-1</sup> and it demonstrated high Cs<sup>+</sup> selectivity and excellent cycling stability. A detailed study indicated that the exceptional HER/OER catalytic activity of MSNS mitigated polarization and expedited electron transfer, thereby augmenting the electrochemical Cs<sup>+</sup> extraction performance.
