Platinum group metals include platinum(Pt), rhodium(Rh), palladium(Pd), ruthenium(Ru), osmium(Os), and iridium(Ir), which belong to precious metals as gold(Au) and silver(Ag). They have extremely strong atomic bonds, and thus have great interatomic bonding force and maximum bulk density. The atomic coordination number of all platinum group metals is 6, which determines their unique physical and chemical properties.
Platinum group metals have high melting points, good electrical conductivity and corrosion resistance, high temperature strength and high temperature creep resistance, and good high temperature stability. These characteristics make them important materials for modern industry and national defense construction, widely used in aviation, aerospace, rockets, atomic energy, microelectronics technology, chemical, glass, gas purification and metallurgical industries, and their role in high-tech industries is increasing. Therefore, it is known as the “vitamin” and “modern new metal” of modern industry.
In recent years, platinum group metals have been increasingly used in industries such as automobile and motorcycle exhaust purification, fuel cells, electronic and electrical industries, dental materials and jewelry. In the challenging 21st century, the development of platinum group metal materials directly restricts the development speed of these high-tech fields, and also directly affects an international position in the world economy.
For example, the research on the electrocatalytic oxidation behavior of small organic molecules such as methanol, formaldehyde, and formic acid, which can be used as fuel cells by nano platinum catalysts has both the significance of basic theoretical research and broad application prospects. Studies have shown that the main catalysts with certain electrocatalytic oxidation activity for small organic molecules are mostly platinum group noble metals.
