A Quick, Efficient and Simple Protocol for Synthesis of Bimetallic Nickel‐Palladium Nanoparticles: Effective Catalyst for Biaryl Synthesis

Abstract

Herein we report a very simple and an efficient protocol for the synthesis of palladium‐nickel bimetallic nanoparticles. Palladium chloride (PdCl2) has been used as precursor for synthesis of Palladium Nanoparticles (Pd Nps). Salting out agent lithium chloride (LiCl) enhanced the reduction rate of Pd (II) and Ni (II) to the corresponding Pd and Ni nanoparticles transformation up to a considerable extent. The methodology adopted resulted nanosized palladium‐nickel bimetallic particles in just a few seconds. The as‐prepared bimetallic nanoparticles were characterized with Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), Energy Dispersive X‐Ray Spectroscopy (TEM‐EDX), X‐Ray Powder Diffraction (XRD), Dynamic Light Scattering (DLS) and Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP AES) analysis. The catalyst with only 0.3 mol% Pd showed its efficiency in Suzuki‐Miyaura cross‐coupling reaction with excellent yield of the desired biaryl products.

Catalytically active nanosized Pd9Te4(telluropalladinite) and PdTe (kotulskite) alloys: first precursor-architecture controlled synthesis using palladium complexes of organotellurium compounds as single source precursors

“…In this context, in recent past, nanosized bimetallic alloys have attracted attention of the researchers as they show improved catalytic activity than monometallic catalysts, at nanoscale, due to the electronic and geometrical modications which arise as a consequence of synergic cooperation between the two metals of alloys. [43][44][45][46][47][48][49][50] In the present study, both Pd 9 Te 4 and PdTe are bimetallic alloys in which active Pd atoms are incorporated in a lattice together with Te. 25,26 Hence, these intermetallic phases are likely to offer the advantage of hosting solid active sites.…”

New conjugated carbazole derivatives: synthesis and photophysical properties catalysed by Pd–Cu@rGO

“…For example, the two metals can donate and accept electrons from each other, which can alter the electronic structure of the nanoparticle and make it more active for certain reactions. 10 The dispersion of bimetallic nanoparticles on carbon-based supports is also an important factor that can affect their catalytic performance. Among all, carbon supports, i.e.…”
