Abstract
Provided is a method of making an inorganic platinum compound. The method includes the steps of: Step (A): providing a platinum material and a halogen-containing oxidizing agent; and Step (B): treating the platinum material with the halogen-containing oxidizing agent in a hydrochloric acid aqueous solution to obtain the inorganic platinum compound, including chloroplatinic acid or chloroplatinate salt; wherein the halogen-containing oxidizing agent excludes chlorine gas. The method of making an inorganic platinum compound is simple, safe, time-effective, cost-effective, and environment-friendly, and has the advantage of high yield.
