General description

Platinum is a heavy precious metal with good resistance to corrosion and chemical attack. Platinum and its alloys are widely used for electrodes, crucibles, and dishes that can be heated to high temperatures. It also has many applications as a catalyst, especially in the field of automotive catalytic converters and petroleum refining.

Application

Platinum mesh is widely used as a counter electrode in various electrochemical reactions. For example, it is used in the preparation of lanthanide-doped TiO2 nanotubes and in recycling captured CO2 using an electrochemical route.
