Summary |
We synthesized GePt3 nanoparticles by a colloidal route, with the purpose of replace or reduce platinum catalyst in hydrogen evolution reaction. Once successfully set up the real-time analysis system, the relationship between hydrogen production rates and loading quantities of GePt3 can be optimized by more detailed analysis. |
Scientific Breakthrough |
A system for preparing of platinum-germanium alloy nanocrystals is provided, which comprises a first supply device for supplying platinum (II) iodide as the precursors of platinum and a second supply device for supplying germanium (IV) iodide as the precursors of germanium. The platinum (II) iodide, oleic acid (OA) and oleylamine (OLA) are added to the first supply device placed on a heating plate, and preheated for 30 minutes at 130℃. Next, germanium (IV) iodide, oleic acid (OA) and oleylamine (OLA) are mixed and reheated to 130℃. Then, the reaction temperature is heated up to 260℃ by a rate of 2℃ /min and once the temperature reached 260℃, the first supply device was cooled instantly to room temperature. The nanoparticles (GePt3) could be obtained, whereas byproduct and unreacted precursors were discarded. We further apply the as-synthesized GePt3 nanoparticles in hydrogen evolution reaction to replace or reduce platinum catalyst. |
