Platinum Nanopowder Water Dispersion (Pt, 3 nm, 500ppm)

Platinum Nanopowder Water Dispersion (Pt, 3 nm, 500ppm) is a highly concentrated colloidal solution of platinum nanoparticles suspended in water. Here’s a detailed breakdown of its key features and applications:

1. Key Features:
   • Platinum (Pt): The primary material in the dispersion is platinum, a precious metal renowned for its excellent catalytic properties, biocompatibility, and resistance to corrosion.
   • Nanoparticles: The platinum particles have an average size of 3 nanometers (nm), providing a high surface area relative to their volume. This results in enhanced reactivity and catalytic efficiency.
   • Water Dispersion: The platinum nanoparticles are uniformly dispersed in water, forming a stable colloidal solution that prevents the particles from aggregating or settling over time.
   • Concentration: The dispersion has a concentration of 500 ppm (parts per million), meaning there are 500 milligrams of platinum nanoparticles per liter of solution.
2. Properties:
   • Small Particle Size: With a size of 3 nm, the platinum nanoparticles exhibit increased surface area and reactivity, which makes them highly effective in catalysis and other chemical applications.
   • High Stability: The dispersion is stabilized to ensure that the platinum nanoparticles remain evenly distributed and do not aggregate over time, preserving the solution’s performance.
   • Catalytic Properties: Platinum nanoparticles are known for their excellent catalytic activity, especially in processes such as hydrogenation, oxidation, and fuel cell applications. Their high surface area enhances their catalytic efficiency.
3. Applications:
   • Catalysis: Platinum nanoparticles are widely used as catalysts in chemical reactions, particularly in hydrogenation and oxidation processes, as well as in reactions that require selective catalysis.
   • Fuel Cells: Platinum is a critical material in proton exchange membrane fuel cells (PEMFCs), where it serves as a catalyst in the conversion of hydrogen and oxygen into electricity.
   • Sensors: Due to their high surface area and reactivity, platinum nanoparticles are used in the development of sensitive chemical and biosensors, where they help in the detection of specific molecules or ions.
   • Environmental Applications: Platinum nanoparticles are used in environmental remediation and catalytic converters to reduce harmful emissions, as well as in processes aimed at cleaning or treating pollutants.
4. Handling and Safety:
   • Toxicity: Although platinum nanoparticles are generally considered biocompatible, they should still be handled with care to avoid inhalation, ingestion, or skin contact. Adhere to appropriate safety guidelines when working with the dispersion.
   • Storage: The dispersion should be stored in a cool, dark place to maintain its stability and prevent nanoparticle aggregation or degradation.
   • Precautions: Always wear appropriate personal protective equipment (gloves, goggles, lab coats) when handling the dispersion. Work in a well-ventilated area or under a fume hood to minimize exposure to airborne particles.

With a concentration of 500 ppm, this dispersion offers a significant concentration of platinum nanoparticles, making it particularly suitable for high-performance applications such as advanced catalysis, fuel cells, and high-sensitivity sensors.
