In this work, state-of-the-art Pd-chelated poly(triazine imide) (Pd-PTI) nanocatalysts were synthesized with PTI, as cheap solid support, and different Pd contents by an easy co-precipitation method for conducting the model reduction reaction of p-nitrophenol to p-aminophenol. The electron microscopy observations (i.e., SEM and transmission electron microscopy), quant. dispersive X-ray spectroscopy and elemental mapping images demonstrated that Pd nanoparticles (NPs) were homogeneously loaded on the surface of highly crystalline two-dimensional (2-D) PTI nanosheets. Among the all prepared Pd-PTI nanocatalysts, the PTI-1500-Pd indicated the highest pseudo-first-order rate constant of 12.7 x 10-3 s-1, which was significantly higher than that of the recently reported Pd-based nanocatalysts. This catalyst showed ultrahigh, superior catalytic efficiency (≥99%) and stability properties for the hydrogenation of p-nitrophenol within 40 s under mild conditions and possessed excellent recovery (≥90%) of expensive Pd NPs after five consecutive cycles. The high-catalytic performance of the PTI-1500-Pd nanocatalyst is related to specific properties of the highly crystalline structure, high-surface area and very available surface amine groups of 2-D PTI nanosheets, which functioned as an active site for immobilizing ultrafine Pd0 NPs. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Product Details of 13820-53-6).
Sodium tetrachloropalladate(II) (cas: 13820-53-6) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Product Details of 13820-53-6
