The 40% Ruthenium on KetjenBlack EC-300J manufactured by Fuel Cells ETC is a fine powder that can be used as a catalyst or electrocatalyst in various electrochemical and chemical applications, such as the following examples:

Hydrogen evolution reaction or HER,
Water splitting reaction,
Electrochemical sensors,
Formic acid dehydrogenation,
On-demand hydrogen generation from ammonia borane, sodium borohydride, and other chemical hydrides via hydrolysis reaction,
Aqueous nitrate/nitrite reduction (denitrification, often yielding NH3/N2),
Catalytic wet air oxidation (for the destruction of recalcitrant organics in wastewater),
Hydrodechlorination of chlorophenols (for water treatment),
Hydrodeoxygenation and hydrogenolysis of lignin-derived phenolics and β-O-4 cleavage (such as phenol to cyclohexane),
Cellulose upgrading (hydrolytic hydrogenation to sorbitol and related polyols),
Sugar/biopolymer upgrading (such as glucose to sorbitol),
Biomass furanics (such as furfural to furfurly alcohol and tetrahydrofurfuryl alcohol),
Biomass platform molecules (such as levulinic acid to γ-valerolactone),
Hydrogenation of nitroarenes to anilines,
Carbonyl hydrogenation in aqueous phase (such as butanone to 2-butanol, lactic acid to 1,2-propanediol),
Selective hydrogenation of α,β-unsaturated aldehydes/ketones,
Hydrogenation of aromatic rings (such as benzene to cyclohexane),
Sabatier reaction (CO/CO2 methanation)
