Platinum Ruthenium Black Catalyst
Platinum Ruthenium Black Catalyst
CAS: 7440-06-4 7440-18-8
Appearance: black powder
Application scope：
Mainly used as catalyst for proton exchange membrane electrolysis of water for hydrogen production, catalyst for hydrogen fuel cell and alcohol fuel cell, etc.
Electrocatalysts for hydrogen evolution and oxygen evolution in membrane electrodes are very important for the whole water electrolysis hydrogen production reaction. An ideal electrocatalyst should have the characteristics of corrosion resistance, good specific surface area, porosity, catalytic activity, electronic conductivity, electrochemical stability, low cost, and environmental friendliness. The cathode hydrogen evolution electrocatalyst is in a strong acid working environment and is prone to corrosion, agglomeration, loss and other problems. In order to ensure the performance and life of the electrolytic cell, the hydrogen evolution catalyst materials are mainly corrosion-resistant Pt precious metals and their Pt-Ru alloys. Compared with the cathode, the anode polarization is more prominent, which is an important factor affecting the efficiency of PEM water electrolysis for hydrogen production. Among them, platinum carbon black catalyst has better activity and better stability; but Pt-Ru alloy is also an alloy electrocatalyst with many applications, which increases the active specific surface area of the catalyst and improves the mechanical strength and chemical stability of the catalyst.
