Platinum Iridium

PLATINUM IRIDIUM ON CARBON CATALYST

P-TECH 0601

BACKGROUND

TFP Hydrogen's PtIr/C Catalyst system is a range of products comprising loading, Pt:Ir ratio and support options. The catalyst has been developed for use in a wide range of applications where corrosion and oxidation tolerance are of critical importance. 

CATALYST SPECIFICATION

TFP Hydrogen has developed a catalyst with a specific Pt:lr ratio and electrochemical active surface area (ECSA), to produce a catalyst demonstrating excellent durability without hindering the catalytic performance. However, we are both flexible with Pt:Ir ratio, metal weight loading, and ECSA to synthesise a product specific to a customer's requirements.

Appearance	Black Powder
Molecular Formula	40 wt.% PtIr/C
Electrochemical Active Surface Area	15 - 30 m2/g
