Abstract:
1. A method for producing a thiometallate or selenometallate material, comprising: mixing a first salt and a second salt in an aqueous mixture under anaerobic conditions, where, during mixing the aqueous mixture has a temperature of from 15° C. to 150° C., and wherein the first salt comprises a cationic component containing one or more metals selected from the group consisting of an alkali metal, an alkaline earth metal, and mixtures thereof and comprises an anionic component containing a first metal selected from the group consisting of Mo, W, and V where the anionic component is selected from the group consisting of MoS separating a solid material from the aqueous mixture comprising a) the first metal of the anionic component of the first salt; and b) the second metal of the cationic component of the second salt and containing at most 0.5 wt.% of the cationic component of the first salt, wherein at least a portion of the solid material separated from the aqueous mixture has a structure according to a formula selected from the group consisting of formula (I), formula (II), formula (III), and formula (IV); where M is either the first metal or the second metal, and at least one M is the first metal and at least one M is the second metal, and Q is either sulfur or selenium; where M is either the first metal or the second metal, and at least one M is the first metal and at least one M is the second metal, Q is either sulfur or selenium, and X is selected from the group consisting of SO 4 , PO 4 , oxalate (C 2 O 4 ), acetylacetonate, acetate, citrate, tartrate, Cl, Br, I, ClO 4 , and NO 3 ; where M is either the first metal or the second metal, and at least one M is the first metal and at least one M is the second metal, Q is either sulfur or selenium, and X is selected from the group consisting of SO 4 , PO 4 , oxalate (C 2 O 4 ), acetylacetonate, acetate, citrate, tartrate, Cl, Br, I, ClO 4 , and NO 3 ; where M is either the first metal or the second metal, and at least one M is the first metal and at least one M is the second metal, Q is either sulfur or selenium, and X is selected from the group consisting of SO 4 , PO 4 , oxalate (C 2 O 4 ), acetylacetonate, acetate, citrate, tartrate, Cl, Br, I, ClO 4 , and NO 3 .
