Engineering non-Pt electrocatalysts that are accompanied with superior activity and durability toward MeOH oxidation reaction (MOR) remains a great challenge. A lamellar and conductive ion association is easily formed by mixing Na2PdCl4, (NH4)6Mo7O24, and cetyltrimethylammonium bromide (CTAB), designated as PdMoCTAB. Through tuning the amounts of precursors, three kinds of Pd supported by lamellar ion association are fabricated by a facile hydrothermal method. Surprisingly, when the at. ratio of Pd and Mo is 1.8:1, the resultant Pd/PdMoCTAB (denoted as Pd1.8Mo) presents great catalytic performance for MOR in an alk. medium with a high peak c.d. of 2178 mA mgmetal-1. The mechanism could be due to the high loading efficiency of Pd on the great surface of ion association, rapid mass transferring in the lamellar structure, and abundant strain defects of Pd induced by the deformation of ion association as well as the good conductivity of PdMoCTAB. Pd1.8Mo also shows improved stability, whereby the c.d. maintains 104 mA mgmetal-1 after electrochem. catalysis for 10,000 s and, after 500 cycles, the mass activity retains ∼64% of the initial value. Such conductive and lamellar PdMoCTAB ion association is expected to become a promising support to load various noble metals for preparing excellent electrochem. catalysts. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Synthetic Route of Cl4Na2Pd).
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. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Synthetic Route of Cl4Na2Pd
