摘要：

A new low-temperature solid-state ion-exchange route has been used to ion-exchange KBi3S5. The new method allows the solid-solid ion-exchange of the K+ ions for the smaller cations Li+ and NaC+ as well as for the NH4+ at the remarkably low temperature regime of 110-130 degrees C. The topotactically ion-exchanged series A(x)K(1-x)Bi(3)S(5) (A = Li, Na, and NH4) was prepared and characterized by powder X-ray diffraction, differential scanning calorimetry, differential thermal analysis, thermal gravimetric analysis, semiquantitative microprobe analyses, solid-state UV/vis/near-IR spectroscopy, and variable-temperature solid-state Li-7 NMR spectroscopy.
