Nickel nanoparticle-poly(N-vinyl-2-pyrrolidone)/TiO 2 -ZrO 2 composite (Ni-PVP/TiO 2 -ZrO 2 ) was prepared by in situ polymerization method. The physical and chemical properties of Ni-PVP/TiO 2 -ZrO 2 were investigated by XRD, FT-IR, BET, TGA, SEM and TEM techniques. The catalytic performance of this novel heterogeneous catalyst was determined for the Suzuki-Miyaura cross-coupling reaction between aryl halides and phenylboronic acid in the presence of methanol-water mixture as solvent. The effects of reaction temperature, the amount of catalyst, amount of support, solvent, and amount of metal for the synthesis of Ni-PVP/TiO 2 -ZrO 2 , were investigated as well as recyclability of the heterogeneous composite. The catalyst used for this synthetically useful transformation showed considerable level of reusability besides very good activity.

“…It should be mentioned that there was very low Pd leaching during the reaction and the catalyst exhibited high stability even after nine recycles (Table 5). Compared to our previous study on prepared composites using SBA-15 [37][38][39][40][41], Pd-PHEMA/ KIT-6 shows more recyclability. It can be related to the interconnected large-pore cage-type mesoporous KIT-6 with three-dimensional (3D) porous networks in comparison to SBA-15 with a two-dimensional (2D) array of pores, because three-dimensional porous network of KIT-6 allows for a faster diffusion of reactants, avoids pore blockage, provides more adsorption sites and can prevent leaching of PHEMA and Pd nanoparticles.…”

“…In our previous report, we prepared mesoporous silica/ polymer composites by using SBA-15 with 2D hexagonal (p6mm) structures [37][38][39][40]. In this study, we focused on the preparation of poly(2-hydroxyethyl methacrylate)/KIT-6 as a good support for Pd nanoparticles, and thus generated a suitable heterogeneous catalyst having a large surface area.…”

Pd nanoparticle-poly(2-hydroxyethyl methacrylate)/KIT-6 (Pd-PHEMA/KIT-6) composite was fabricated through in situ polymerization method and was evaluated as a novel heterogeneous catalyst in SuzukiMiyaura cross coupling reactions of aryl halides and phenylboronic acid in an aqueous medium. The catalyst was characterized by XRD, FT-IR, UV-Vis, TG, BET, and TEM techniques. The results revealed that the supported catalyst Pd-PHEMA/KIT-6 exhibited excellent catalytic activity for the coupling of aryl iodides, aryl bromides, and aryl chlorides. This heterogeneous catalyst could be reused at least nine times without any decrease in activity.

“…Due to their elasticity, organic functionalities, transparency, stability, hardness and chemical and thermal stability, the polymers, co‐polymers and their modified structures are considered as ideal supports. Therefore, the design and preparation of organic–inorganic hybrid polymers with new and versatile scaffolds as heterogeneous catalysts are in much demand …”

Poly (styrene‐co‐maleic anhydride) (SMA) was modified by reactionwith4‐amino‐2‐methyl‐10H‐thiene [2,3‐b][1,5]‐benzodiazepine (ATD) hydrochloride, providing an imide with the appropriate sites for the coordination of Cu(I)ions. This modified SMA was reacted with CuI to obtain immobilized Cu(I) NPs. This Cu(I) NPs (CuI/SMI‐TD) was fully characterized by conventional techniques such as FT‐IR, NMR, SEM, TEM, EDAX and ICP‐AES analysis. The SEM and TEM images clearly showed CuI NPs as spherical shapes and the size of particles is 30‐60 nm. Moreover, a quantitative description for experimental features of CuI/SMI‐TD was presented via computational assessment for the interactions between copper metal ions and coordination sites of SMI‐TD ligand. The catalytic activity of this new catalyst was examined in the regioselective synthesis of 1,4‐disubstituted‐1,2,3 triazoles in a classical copper‐catalyzed reaction a so‐called click reaction. The catalyst showed highly efficient catalytic activity, excellent reusability, high yield and more importantly excellent, regioselectivity. The catalyst was recoverable through simple filtration and can be reused at least five times without significant loss of catalytic activity. The heterogeneous nature of the catalyst was confirmed based on the hot filtration test and ICP‐AES analysis.
