| titleOfInvention | High-purity spongy platinum and preparation method and application thereof |
| abstract | The invention relates to high-purity sponge platinum and a preparation method and application thereof, wherein the high-purity sponge platinum is prepared by the following steps: (1) carrying out alkali fusion on the crude platinum; (2) preparing soluble platinum salt; (3) removing impurity ions; (4) preparing platinum oxide; (5) removing alkali metal ions; (6) preparing high-purity spongy platinum, and obtaining the spongy platinum through the six steps; then, chloroplatinic acid is prepared through (1); (2) preparing a dispersing agent; (3) preparing an intermediate; (4) preparing a reducing solution; (5) the four steps obtain the platinum powder with high specific surface area. Compared with the prior art, the invention has the advantages of no generation of nitrogen oxide gas, obvious reduction of vanadium and vanadium oxides, iron, magnesium and other base metal oxides, high purity, large and controllable specific surface area and the like. |
