Palladium-supported cobalt hydroxide (Co(OH)2-Pd) nanoplates were fabricated in an aqueous solution and employed as a catalyst for the reduction of 4-nitrophenol. For the preparation of Co(OH)2-Pd, Pd nanoparticles were anchored on the Co(OH)2 nanoplates after the reduction of Na2PdCl4 by ascorbic acid in the absence of a stabilizer at room temperature The observations under transmission and SEM reveal that Pd nanoparticles with a size of 2-5 nm are uniformly dispersed on the surface of the Co(OH)2 nanoplates. In catalytic test, the conversion of 4-nitrophenol to 4-aminophenol is completed within 6 min in the presence of Co(OH)2-Pd(1000) nanoplates with 2.18 at.% Pd, and the corresponding kinetic constant is 0.0089 s-1 in the first test. The catalyst retains relatively high activity after several cycles. The results demonstrate that the Co(OH)2-Pd(1000) nanoplates exhibit high catalytic activity toward the reduction of 4-nitrophenol in the presence of NaBH4. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Category: chlorides-buliding-blocks).
Sodium tetrachloropalladate(II) (cas: 13820-53-6) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Category: chlorides-buliding-blocks
