METHOD FOR PREPARING NANOPARTICLES OF Ni-Sn ALLOYS AND THE USE THEREOF IN REFORMING REACTIONS

摘要

The invention relates to a method for preparing Ni-Sn nanoparticles, consisting in: preparing a solution of a nickel carboxylate, in which said carboxylate has between 1 and 6 carbon atoms, and a tin halide in an organic solvent; adding polyvinylpyrrolidone (PVP); stirring same until a uniform solution is obtained; adding an inorganic reducing compound; refluxing same, thereby obtaining a colloidal solution; and adding an organic polar solvent to the previously produced colloidal solution, thereby causing the precipitation of a solid. The invention also relates to the use of these particles in reforming reactions.
