The present disclosure is related to a process for obtaining catalysts based on metallic nanoparticles supported in a polymeric matrix, characterized in that it comprises the following steps: (I) preparing the water insoluble polymer matrix support, where the polymer may be organic or inorganic-organic; (II) loading the catalytically active phase into the polymer matrix support, in such a way that said catalytically active phase will also be charged on the surface of said matrix using for this purpose inorganic salts solutions of metal precursors in an aqueous acid medium with a pH of 0 to 4, where the metals are selected from the group comprising the metals of groups 4, 8, 10 and 11 of the periodic table, and the total metal concentration in the solution is between 15 and 60 mg / l; and, (III) obtaining the catalytically active phase (obtaining the nanoparticles), reducing the metal that is both in the interior as well as on the surface of the polymeric support through a process of c hemical reduction Using a reducing agent. |
