This work reports the synthesis of a new quasi two-dimensional layered compound, K(HO) WS, for aqueous potassium ion storage. Its crystal structure determined by single crystal X-ray diffraction is composed of WS layers and disordered hydrated K stacking along the direction alternately. Due to the large interlayer spacing and high conductivity, K(HO) WS is demonstrated to be a stable host for reversible intercalation and de-intercalation of hydrated K in KSO aqueous solution.
这项工作报道了一种用于水相钾离子存储的新型准二维层状化合物K(HO)WS的合成。通过单晶X射线衍射确定的其晶体结构由WS层和沿方向交替排列的无序水合K堆积组成。由于层间距大且电导率高，K(HO)WS被证明是KSO水溶液中用于水合K可逆嵌入和脱嵌的稳定主体。
