Platinum nano powder: Platinum is a malleable, ductile and lustrous silvery-white metal. It is uninfluenced by air and water, however, will dissolve in hot aqua regia. It is also dissolved in hot concentrated phosphoric and sulphuric acids, and in molten alkali. It is used as resistant as gold to corrosion and tarnishing. Moreover, platinum will not oxidize in air no matter how strongly it is heated.

Pt nanocatalysts, nanosized Pt on different supporter has good spatial separation and exhibits excellent catalytic activity with long-term stability. Platinum nanoparticles (Platinum Nano Powder) are auspicious nanoparticles, exhibiting remarkable catalytic activity, able to reduce the intracellular reactive oxygen species (ROS) levels and reduce the downstream pathways leading to inflammation. Platinum's corrosion resistance and high-temperature stability make it ideal as a catalyst in chemical reactions.

The platinum nano powder used in the anti-inflammatory and their potential applications in nanomedicine. Also, the stability of PtNs is of great importance to the development of efficient and durable proton exchange membrane fuel cells and the coalescence of PtNs is responsible for a reduction in the electrochemically active surface area that reduces cell performance.

Platinum nano powder: Platinum containing films could be employed for enzyme immobilization and optical applications. For instance, the enhanced catalytic activity of PtNs plays an important role in the reduction of pollutant gases exhausted from automobiles.  Platinum can be used for both its conductive properties in pacemakers' electrodes, as well as aural and retinal implants, and for its anti-cancer properties in drugs.

Platinum nano powder is used widely in the electronics industry for the manufacture of conductive thick film circuits and internal electrodes of multilayer ceramic capacitors. Platinum is used in computer and in the glass of computer screen. Platinum is used to make fiberglass, liquid-crystal display (LCD) glass and flat-panel displays, and cathode-ray tubes.
