The preparation of palladium metal catalysts supported on carbon part II: Deposition of palladium and metal area measurements

摘要: Abstract Four techniques for Pd deposition were compared and various carbons from Part I used. Increasing burnoff produced higher area of the support available metal area. However, excessive removal carbon resulted in a decrease given loading. Although HNO 3 treatment did not produce an increase area, there significant increases catalyst areas some techniques. Carbon appeared to block micropores extent, but was disappointing found on these samples. A favorable technique would seem be use 15 20% followed by acid washing impregnation adsorption method.
