Terpyridine-based Pd(ii)/Ni(ii) organometallic framework nano-sheets supported on graphene oxide—investigating the fabrication, tuning of catalytic properties and synergetic effects

Abstract

The synergistic effect between Ni and Pd atom was the crucial factor for enhancing catalytic activity.

Carbon-Based Materials for the Development of Highly Dispersed Metal Catalysts: Towards Highly Performant Catalysts for Fine Chemical Synthesis

“…The catalyst was reused four consecutive times without significant sacrificing activity. In Ren et al (2020), a novel terpyridine-based hetero-bimetallic Ni/Pd nanosheet supported on graphene oxide was synthesized, exhibiting higher catalytic activity, substrate applicability and recyclability for the Suzuki coupling reaction under mild conditions [43]. On the electrocatalysis field, Sánchez-Page et al (2020), have determined the influence of graphene sheet properties as supports of iridium-based N-heterocyclic carbene hybrid materials on water oxidation [44].…”

Pd/Cu2O/CuO as Active Sites on the Cyclometalated Pd(II)/Cu(II) Nanosheet: Active Centre Formation, Synergistic and Catalytic Mechanism

“…[12,17,[29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47] Meanwhile, appropriate supports improving dispersion and utilizing have been intensely investigated for improving the catalytic activity, [48][49][50] in which the graphene oxide (GO) was recognized as an ideal one because of its physical properties, such as high stability, large surface area, unique 2D. [51] Ligand design and selection are also an integral part in catalyst, [52] in which a privileged Schiff-base ligand can coordinate with various metals and control metal performance during the catalytic transformations. [53] Especially, cyclopalladated ferrocene Schiff-base derivatives ligand, as one of the most important organometallic compounds, are particularly interesting because of their much more application.…”

A New ternary organometallic Pd(ii)/Fe(iii)/Ru(iii) self-assembly monolayer: the essential ensemble synergistic for improving catalytic activity

“…[57][58][59][60] Graphene oxide as an efficient support was recognized as one of the ideal candidates because of its large surface area, high stability, unique two-dimensional structure. 61,62 Thus, there are a variety of functional groups through which covalent self-assembly lms can be anchored. [63][64][65] Ligand design is also an integral part of the heterogeneous catalyst, and is promising for tuning the metal coordination sphere and stabilizing the active sites available for substrate binding during catalytic cycling.…”
