VULCAN XC72 is widely used in research and development for numerous antistatic and conductive purposes, particularly as a catalyst support. Its high specific surface area and excellent electrical conductivity contribute to enhanced performance in proton-exchange membrane fuel cells (PEMFC), outperforming materials such as acetylene black. Vulcan XC72′s adaptability facilitates the creation of catalyst composites, where catalyst nanoparticles may be either uniformly dispersed and deposited onto the carbon black substrate or synthesized in situ. The material′s extensive surface area is instrumental in regulating the size of catalyst nanoparticles, with evidence suggesting that carbon blacks with larger surface areas tend to produce smaller nanoparticles. Beyond fuel cell applications, Vulcan XC72 has also been employed as a catalyst support in various battery technologies, including redox flow batteries and metal-air batteries, such as zinc-air and sodium-air, where its properties enhance the overall electrochemical performance.
