[1] Chalcogels preferentially absorb heavy metals,[2] such as mercury, lead, and cadmium, from water.
[7] The synthetic method can be extended to many thioanions, including tetrathiomolybdate-based chalcogels.
[8][9][10] When the gels are dried aerogels with high surface areas are obtained and the materials have multifunctional nature.
The above mentioned conditioning makes the gas suitable for a number of applications in fuel cells.
Chalcogels were shown to be very effective at capturing radionuclides from nuclear waste such as 99Tc, and 238U, and especially 129I.
