Abstract

The present invention is directed to a composition comprising a solid material comprised of a first metal/metalloid comprised of a metal or metalloid selected from the group consisting of Cu, Fe, Ag, Co, Mn, Zr, Zn, Sn, Re, Rh, Ru, Pd, Ir, Pt, B, Al, Ce, La, Pb, Cd, Sb, Ge, Ga, In, Bi, and Au; and a second metal selected from molybdenum, tungsten, or vanadium, where the first metal/metalloid and the second metal form a bimetallic tetrathiometallate or a bimetallic tetraselenometallate with sulfur or with selenium. The solid material is comprised of particles and has a particle size distribution, where the mean particle size of the particle size distribution is from about 50 nm to about 5 μm.

Claims

1. A composition comprising:

a solid material, comprised of;

a first metal/metalloid comprised of a metal or metalloid selected from the group consisting of Cu, Fe, Ag, Co, Ni, Mn, Zr, Zn, Sn, Re, Rh, Ru, Pd, Ir, Pt, B, Al, Ce, La, Pr, Sm, Eu, Yb, Lu, Dy, Pb, Cd, Sb, Ge, Ga, In, Bi, and Au; and

a second metal selected from molybdenum, tungsten, or vanadium;

where at least a portion of the solid material is comprised of the first metal/metalloid and the second metal bridged by, and bonded to, sulfur or selenium atoms according to a formula selected from the group consisting of formula (I), formula (II), formula (III), and formula (IV);

2. The composition of claim 1 wherein the solid material has a BET surface area of from 50 m²/g to 500 m²/g.

3. The composition of claim 1 wherein the solid material has a particle size distribution with a median particle size of from about 50 nm to about 5 μ

m.

4. The composition of claim 1 wherein the solid material has a particle size distribution in which the mean particle size of the particle size distribution is from about 75 nm to about 1 μ

m.

5. The composition of claim 1 wherein the solid material contains at most about 0.01 wt. % oxygen.

6. The composition of claim 1 wherein the solid material contains less than 0.5 wt. % of an alkali metal or an alkaline earth metal.

7. The composition of claim 1 wherein the solid material is at least 50% crystalline.

8. The composition of claim 1 wherein the solid material contains less than 0.5 wt. % of ligands other than sulfur-metal bonded complexes between sulfur and the first metal/metalloid or between sulfur and the second metal, or selenium-metal bonded complexes between selenium and the first metal/metalloid or between selenium and the second metal.

9. The composition of claim 1 wherein at least a portion of the solid material is comprised of the first metal/metalloid and the second metal bridged by, and bonded to, sulfur or selenium atoms according to a formula selected from the group consisting of formula (VII), formula (VIII), formula (IX), and formula (X):

10. A composition, comprising:

a solid material comprised of;

a first metal/metalloid comprised of a metal or metalloid selected from the group consisting of Cu, Fe, Ag, Co, Mn, Zr, Zn, Sn, Re, Rh, Ru, Pd, Ir, Pt, B, Al, Ce, La, Pr, Sm, Eu, Yb, Lu, Dy, Pb, Cd, Sb, Ge, Ga, In, Bi, and Au; and

a second metal selected from molybdenum, tungsten, or vanadium;

where the solid material is comprised of at least three linked chain elements, the chain elements being comprised of a first chain element including the first metal/metalloid and having a structure according to formula (V) and a second chain element including the second metal and having a structure according to formula (VI)

11. The composition of claim 10 wherein the solid material has a BET surface area of from 50 m²/g to 500 m²/g.

12. The composition of claim 10 wherein the solid material has a particle size distribution with a median particle size of from about 50 nm to about 5 μ

m.

13. The composition of claim 10 wherein the solid material has a particle size distribution with a mean particle size of from about 75 nm to about 1 μ

m.

14. The composition of claim 10 wherein the solid material contains at most about 0.01 wt. % oxygen.

15. The composition of claim 10 wherein the solid material contains less than 0.5 wt. % of an alkali metal or an alkaline earth metal.

16. The composition of claim 10 wherein the solid material is at least 50% crystalline.

17. The composition of claim 10 wherein the solid material contains less than 0.5 wt. % of ligands other than sulfur-metal bonded complexes between sulfur and the first metal/metalloid or between sulfur and the second metal, or selenium-metal bonded complexes between selenium and the first metal/metalloid or between selenium and the second metal.
