Download or read book Properties of Platinum Catalysts Supported on Carbon Blacks written by and published by . This book was released on 1996 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical and gas-plasma treatments were used to modify chemical/physical properties of carbon black powder commonly used to support platinum catalysts. Altered catalyst-carbon interactions affect catalyst-particle size, which can, in turn, affect catalyst activity and subsequent catalyst life. We have demonstrated that particle size of deposited platinum on carbon can be changed by carbon black pretreatments These modifications can be easily applied to carbon blacks used in fuel cells, high powered batteries, and a variety of chemical reactions where noble metal catalysts are supported on high surface area carbon blacks.
