Claim 14:
15. A process for making a supported nanoparticle composition, comprising:
(I) providing a nanoparticle dispersion comprising a liquid medium and a plurality of nanoparticles distributed therein, wherein each nanoparticle comprises a kernel, the kernels have an average particle size from 4 to 100 nm and a particle size distribution of 20% or less; the kernels comprise oxygen, a metal element M1, optionally sulfur, optionally phosphorus, optionally a second metal element M2, and optionally a third metal element M3, where:
M1 is selected from Mn, Fe, Co, or a combination of two or more thereof;
M2 is selected from Ni, Zn, Cu, Mo, W, Ag, and combinations thereof;
M3 is selected from Y, Sc, alkaline metals, the lanthanides, group 13, 14, and 15 elements, and combinations thereof; and
the molar ratios of M2, M3, S, and P, if any, to M1 is r1, r2, r3, and r4, respectively, 0≤r1≤2, 0≤r2≤2, 0≤r3≤5, and 0≤r4≤5; and

(II) disposing a quantity of the nanoparticle dispersion on a support to obtain a supported nanoparticle composition.
