Abstract

A new low-temperature solid-state ion-exchange route has been used to ion-exchange KBi 3 S 5 . The new method allows the solid-solid ion-exchange of the K + ions for the smaller cations Li + and Na + , as well as for the NH + 4 at the remarkably low temperature regime of 110-130°C. The topotactically ion-exchanged seriesA x K 1-x Bi 3 S 5 (A=Li, Na, and NH 4 ) 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 7 Li NMR spectroscopy.
