概要

詳細

This product is a British-imported platinum black catalyst, developed for high-performance applications in fuel cells, electrochemical sensors, hydrogen electrodes, and catalytic chemical synthesis. As a finely divided black powder with a platinum content exceeding 95% on a dry basis, it offers a specific surface area of approximately 60 m²/g, which supports enhanced catalytic activity for key reactions such as oxygen reduction and hydrogen oxidation. With low moisture content (<1%) and total metallic impurities below 320 ppm, the material ensures consistent performance in proton exchange membrane, alkaline, direct methanol, and microbial fuel cells, as well as in gas and biosensor systems. Its fine particle size (X-ray diffraction size under 75 µm) facilitates efficient electrode modification and improved reaction kinetics, making it a reliable choice for advanced energy and electrochemical research.

This is an anti-bidding price. Due to the large fluctuations in precious metal prices, please consult customer service for the real-time price.

Platinum black catalysts are commonly used in fuel cells, sensors, hydrogen electrodes, chemical synthesis, chemical analysis, electronics, optics and other fields.
Hydrogen electrode: Platinum black is an ideal hydrogen electrode material. Due to its extremely high specific surface area and excellent catalytic activity, it can greatly reduce the overpotential of hydrogen evolution and oxidation reaction.
Fuel cell electrode: In proton exchange membrane fuel cell (PEMFC) and alkaline fuel cell (AFC), platinum black is often used to modify the electrode. It can accelerate the oxygen reduction reaction (ORR) and hydrogen oxidation reaction (HOR), and improve the energy conversion efficiency of fuel cells. In PEMFC, platinum black can effectively reduce the dynamic polarization in the process of ORR, and can also be used in direct methanol fuel cell (DMFC), microbial fuel cell (MFC) and phosphoric acid fuel cell (PAFC).
Electrochemical sensors: used to prepare various electrochemical sensors, such as gas sensors (detecting hydrogen, oxygen, etc.) and biosensors. In the electrochemical sensor for the detection of hydrogen, the platinum black electrode can quickly absorb hydrogen and generate a measurable current signal through the electrochemical oxidation reaction to achieve high sensitivity detection of hydrogen concentration.
