PREPARATION METHOD OF INORGANIC FILLER ADHERED PALLADIUM-PLATINUM ALLOY |
摘要 |
A preparation method of an inorganic filler dopped with a Pd-Pt alloy is provided, wherein a prepared inorganic filler can be used usefully in a hydrogen fuel system process of a nuclear fusion reactor since the inorganic filler has merits that the hydrogen isotopes are separated easily within a short time as compared with a conventional filler of columns for gas chromatography used for separating hydrogen isotopes, and the inorganic filler can be used at a room temperature. A preparation method of an inorganic filler dopped with a Pd-Pt alloy comprises: a first step of dissolving a Pd precursor and a Pt precursor into a solvent mixture of water and alcohol, and adding inorganic particles into the dissolved solution to impregnate surfaces of the inorganic particles with a Pd-Pt alloy; a second step of drying and sintering a solution of the inorganic particles impregnated with the Pd-Pt alloy; and a third step of heat-treating the sintered particles to crystallize the Pd-Pt alloy on the surfaces of the inorganic particles. The preparation method further comprises a step of adding a polymer into the solvent mixture of the first step. The preparation method comprises dissolving a Pd precursor and a Pt precursor into a solvent mixture of water and alcohol and adding inorganic particles into the dissolved solution such that surfaces of the inorganic particles are dopped with a Pd-Pt alloy by a reduction action of the alcohol. |
