This page presents a compact yet complete introduction to the Iridium based catalyst portfolio, including carbon-supported Ir/C catalysts, unsupported Ir black and iridium oxide powders, as well as Ir-RuO2 composite black catalyst. These materials are suitable for fuel cells, electrolyzers, sensors, and a broad range of electrochemical R&D workflows where conductivity, catalytic activity, stability, and reproducible material quality matter.
The Iridium based catalyst lineup covers multiple material architectures to support screening, benchmarking, durability evaluation, and catalyst ink or electrode preparation for academic and industrial research.
Carbon-supported iridium catalysts based on Vulcan XC-72 or Ketjen Black provide a practical route to balance metal utilization, dispersion, and accessible surface area. They are well suited for ink formulation and comparative electrocatalyst studies.
Unsupported iridium black, conductive IrOx, and conductive IrO2 powders are useful when researchers need carbon-free catalyst systems, oxide-rich surface chemistry, or better compatibility with anodic environments.
The Ir-RuO2 composite black catalyst offers a mixed-metal pathway for studies involving noble-metal synergy, oxygen evolution behavior, and electrochemical stability in demanding operating conditions.
Browse the main catalyst groups to identify the most suitable iridium catalyst architecture for your research workflow.
Available in 5%, 10%, 20%, and 40% nominal Ir loading. A practical option for catalytic screening, fuel cell catalyst studies, electrolyzer research, and sensor development.
40% Ir supported on Ketjen Black offers higher catalyst BET surface area than the Vulcan-based counterpart, which may be attractive for dispersion-focused or support-comparison studies.
Includes high-surface-area Ir black, conductive IrOx powder with a core-shell style description, and conductive IrO2 powder with enhanced thermal-treatment stability.
A 1:1 ratio composite black catalyst designed for mixed-metal and oxide-rich noble-metal electrocatalysis research, especially where Ir/Ru synergy is of interest.
