Resumen

AMMONIUM HEXACHLOROPLATINAE (Pt(NH4)2Cl6) HAS BEEN PROVEN TO BE A GOOD PRECURSOR TO OBTAIN METALLIC Pt BY THERMAL DECOMPOSITION, IN ADDITION TO BEING A STABLE COMPOUND EASILY OBTAINED FROM A VARIETY OF Pt RECUPERATION PROCESSES. THIS WORK WAS AIMED TO DEVELOP A SIMPLE WAY TO SYNTHESIZE Pt(NH4)2Cl6. THE CRYSTALLOGRAPHIC CHARACTERIZATION BY POWDER AND SINGLE CRYSTAL XRD IS REPORTED, ALONG WITH A SIMULATION OF THE XRD PATTERNS PERFORMED WITH THE SOFTWARE CERIUS. A THERMOGRAVIMETRIC ANALYSIS (TGA) ALLOWED INSIGHT INTO THE THERMAL DECOMPOSITION PROCESS, WHICH HAS BEEN CONFIRMED TO TAKE PLACE IN TWO STEPS, BETWEEN 175 AND 400°C. THIS LOW DECOMPOSITION TEMPERATURE MAKES Pt(NH4)2Cl6 AN IDEAL CATALYST PRECURSOR TO OBTAIN Pt/C FOR POLYMER ELECTROLYTE MEMBRANE FUEL CELL (PEMFC) ELECTRODE FABRICATION.
