Abstract
Amorphous metal chalcogenides having the formula A2xSnxSb3-xQ6 are provided. In the chalcogenides, A is an alkali metal element, such as K or Cs, and Q is S or Se. The value of x can be in the range from 0.8 to 1. Porous chalcogenide materials made from the amorphous chalcogenides are also provided. These porous materials comprise metal chalcogenides having the formula (AB)2xSnxSb3-xQ6, wherein x is in the range from 0.8 to 1, A and B are two different alkali metal elements, and Q is S or Se.
