“…This can be addressed by using heterogeneous catalysts as suitable alternatives, which are mostly recyclable [3] . Metal nanoparticles (MNPs) have high surface area as well as high surface energy rendering them to be capable of showing promising catalytic activity [4–6] . However, smaller MNPs often aggregate to form larger one due to their high surface energy which ultimately results into loss in catalytic activity.…”

Organic polymer networks (OPNs) are an interesting class of materials showing immense potential for supporting various metal nanoparticles for their heterogeneous catalytic applications. Herein, we delineate a protocol for generating metal‐based nanoparticles including silver nanoparticles (AgNPs) and ruthenium nanoparticles (RuNPs) within a phosphate‐based OPN (OPN‐4) prepared by the copolymerization of phosphoryl chloride and 1,3,5‐(4‐hydroxyphenyl)benzene in order to generate the heterogeneous catalysts, M@OPN‐4 (M=Ag/Ru). OPN‐4 emerged as an excellent host for the loading of these nanoparticles. These nanoparticles loaded OPN‐4 were characterized by several techniques including scanning and transmission electron microscopy (SEM, TEM), thermogravimetric analysis (TGA), X‐ray photoelectron spectroscopy (XPS), powder X‐ray diffraction (PXRD), and FTIR studies. M@OPN‐4 acted as the heterogeneous catalysts towards various organic reactions including reduction of nitroaromatics (Ag@OPN‐4) and oxidation of benzyl alcohols (Ru@OPN‐4) furnishing desired products from moderate to excellent yield with high selectivity over a broad range of substrates. They also exhibited easy recovery via filtration and reuse for up to five cycles without losing their catalytic activity significantly. Above all, the as synthesized catalysts were found to possess air and moisture endurance, high cost‐effectiveness and robust behavior. Thus, the OPN‐4 nanocontainer could establish itself as a versatile host towards different metal nanoparticles attributed to electron donating phosphate moiety.

N-heterocyclic carbene (NHC)-palladium(II) complex (GO@NHC-Pd) was synthesized on graphene oxide (GO) support via a simple and cost-effective multistep approach. The spectroscopic, microscopic, thermal, and surface analyses of GO@NHC-Pd confirmed the successful formation of the catalyst. The investigation of catalytic activity showed that GO@NHC-Pd was very effective in Suzuki-Miyaura as well as Hiyama cross-coupling. Being heterogeneous in nature, GO@NHC-Pd was recovered after each reaction cycle easily and reused for up to nine and six cycles in Suzuki-Miyaura and Hiyama cross-coupling, respectively, without significant loss of activity. Further exploration of the supercapacitor performance of GO@NHC-Pd catalyst assembled in a twoelectrode cell configuration shown a maximum attained capacitance of 105.26 F/g at a current density of 0.1 A/g with good cycling stability of 96.89% over 2,500 cycles.

An Efficient Recyclable Polymer Supported Palladium Catalyst for Suzuki Reaction in Water

This work describes the development of an efficient and reusable heterogeneous polymer supported palladium catalyst for Suzuki reaction in water. This novel catalyst system was designed through monoethanolamine (MEA) modification of nitrile group in Polyacrylonitrile (PAN) followed by metal salt (PdCl2) complexation. The resulting polymer complex (mPAN‐Pd) was then successfully optimised as an efficient heterogeneous catalyst for Suzuki reaction under ligand free conditions. The supported catalyst provided excellent reactivity in the coupling reactions of a series of aryl halides with phenyl boronic acids under mild reaction condition. The reaction proceeded in presence of 2 mol % of mPAN‐Pd catalyst at 80 °C in water and the resulting products were isolated in moderate to excellent yields upto 98 %. Furthermore, this catalyst can be conveniently recovered by simple filtration and reused at least five times without an appreciable loss in its activity or Palladium leaching.
