Application

Nanoscale platinum powders possess improved reaction rates compared to bulk powders owing to their high surface area. Platinum nanopowders have found use in applications including in fuel cells and oxidation catalysts.

Features and Benefits

High catalytic functionality, high conductivity and chemical stability in an acid-base environment.

General description

Platinum nanopowder has a high catalytic activity and is used widely in catalysis, batteries, fuel cells, capacitors and sensors. They are used in the synthesis of counter electrode in dyes sensitized solar cells. Since it is difficult to directly use platinum nanoparticle as the electrode, they are usually surface supported on graphene or multi-walled carbon nanotubes.
