Owing to their high catalytic efficiency and selectivity, the ordered intermetallic Pd-based nanocatalysts have greater promise than disordered nanocatalysts for formic acid oxidation reactions (FAOR). Traditionally, intermetallic nanoparticles are synthesized via the annealing of disordered alloy in a high temperature and reducing atm. However, this method inevitably adds complexity and increases cost to practical application as well as leads to the destruction of nanostructures and the deactivation of nanocatalysts. Herein, monodisperse ordered intermetallic PdCu nanocatalysts are obtained through liquid phase reduction reaction in one pot without heat treatment. The results indicate that the ethylene glycol and KBr not only affect the solubilities of Pd and Cu precursors, but also facilitate the formation of the ordered intermetallic PdCu nanostructures with well-defined morphol. Compared to disordered PdCu, com. Pd/C, and com. Pd black nanocatalysts, the ordered intermetallic PdCu nanocatalysts display enhanced activity and durability for FAOR. The mass and specific activities are 665 mA mgPd-1 and 1.88 mA cm-2, which are 1.45, 2.67, and 4.16 and 1.21, 1.53, and 1.74 times disordered PdCu, com. Pd/C, and com. Pd black nanocatalysts, resp. This work comes up with one novel approach for the preparation of ordered intermetallic PdCu nanocrystals without heat treatment. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Quality Control of Sodium tetrachloropalladate(II)).
Sodium tetrachloropalladate(II) (cas: 13820-53-6) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Quality Control of Sodium tetrachloropalladate(II)
