The XT 30% Platinum on Vulcan XC-72R Grade S manufactured by Fuel Cells ETC is a fine powder that can be used as an electrocatalyst in electrochemical devices and as a heterogeneous catalyst for the synthesis of various organics, such as the following examples:

As the anode and cathode electrocatalysts for proton exchange membrane (PEM) fuel cells. In fact, Pt/C has been one of the most commonly used anode and/or cathode electrocatalyst for membrane electrode assemblies used in the commercial H2/Air PEM fuel cell stacks. Hydrogen oxidation reaction (HOR) is the main anode reaction. Oxygen reduction reaction (ORR) is the main cathode reaction.
As the cathode electrocatalyst for proton exchange membrane (PEM) electrolyzers. Hydrogen evolution reaction (HER) is the main cathode reaction.
As the anode and cathode electrocatalysts for alkaline fuel cells (AEM-based or liquid alkaline electrolyte-based). Hydrogen oxidation reaction (HOR) is the main anode reaction. Oxygen reduction reaction (ORR) is the main cathode reaction.
As the cathode electrocatalyst for direct methanol fuel cells (DMFCs). Oxygen reduction reaction (ORR) is the main cathode reaction.
As the cathode electrocatalyst for direct ethanol fuel cells (DEFCs). Oxygen reduction reaction (ORR) is the main cathode reaction.
As the working electrode catalysts in electrochemical gas sensors such as amperometric gas sensors for the detection of H2, O2, CO, etc.
Pt/C modified electrodes to enhance signal in enzymatic sensors.
As the reference/counter electrodes to establish a baseline or benchmark electrode via RDE for ORR, HOR, small-molecule oxidation, and durability testing
As the catalytic hydrogenation catalyst in organic synthesis such as hydrogenation of C=C, C≡C, C=O, nitriles, and heteroaromatic rings in pharma and fine-chem production; often as a cleaner alternative to Pd/C in sensitive molecules.
As a catalyst for the reduction of nitroaromatics to aromatic amines such as hydrogenation of nitrobenzene and halogenated nitroaromatics to anilines and related intermediates.
As a catalyst for the hydrogenation/dehalogenation of chlorinated aromatics such as hydrogenate and partially or fully dehalogenate chlorinated nitro- and amino-aromatics, relevant to both fine-chemistry and detoxification of legacy chlorinated compounds.
As a catalyst for the release of hydrogen from chemical hydrogen carriers such as dehydrogenation of dimethylamine–borane and similar carriers, enabling on-demand H₂ release in portable storage concepts.
As a catalyst for the continuous-flow hydrogenation systems for Pharma/Fine Chemicals such as Pt/C-packed flow reactors are increasingly used for safer, scalable, continuous hydrogenation of aromatic nitro compounds into high-value amines (pharma APIs, dyes, agrochemicals).
and many other electrochemical or non-electrochemical applications.
