    摘要: At least one embodiment includes a method for fabricating a catalyst comprising a colloidal suspension of nanoparticles, the nanoparticles comprising intermetallics of two or more metals exhibiting long range superlattice crystal ordering. The method comprising the steps of: producing a bulk target of the intermetallics of two or more metals exhibiting long range crystal ordering and submerging the target in a solvent. A pulsed laser is used to ablate bulk target material and to produce nanoparticle of the intermetallics of two or more metals exhibiting long range crystal ordering. At least one embodiment includes a catalyst made with the method. The catalyst can exhibit some desirable properties. For example, the catalyst may remain suspended in solution, essentially without surface modification by ionic compounds. Furthermore, the concentration of elements other than those which comprise the solvent or the intermetallic compound may be less than about 1 ppm.
