Article Abstract
This study sought to synthesize supported palladium nanocatalysts that are, in general, convenient to synthesize, suitable for mild conditions, recyclable, and stable in water. The sol-gel procedure was successfully extended to synthesize mesoporous metal oxides with well-dispersed palladium nanoparticles. The resulting catalysts were extensively characterized using techniques such as TEM, powder XRD, SEM-EDX, thermogravimetric analysis, and BET surface area measurements. The catalytic activity of the prepared heterogeneous palladium nanoparticles supported on mesoporous oxides was investigated in terms of C-N and C[triple bond, length as m-dash]C coupling reactions, yielding products of alkynes and -arylamines. Specifically, alkynes were effectively cross-coupled with various aryl iodides and aryl bromides, yielding diaryl alkynes with high efficiency and minimal catalyst loss. Similarly, the Buchwald-Hartwig amination reaction produced its desired products with high selectivity and yield.

The palladium-catalyzed Suzuki-Miyaura cross coupling reaction to forge carbon-carbon bonds fundamentally changes the practice of organic synthesis. Herein an isolated palladium catalyst supported on polymeric carbon nitride (Pd/PCN) for efficient cross coupling of bromobenzene and phenylboronic acid at room temperature is reported. It is demonstrated that the Pd/PCN catalyst with a 2 wt% Pd loading achieves the highest mole-specific activity.

This study presents the successful immobilization of a methotrexate-palladium complex onto the surface of magnetic CoFeO nanoparticles through a simple and cost-efficient process. The environmentally friendly heterogeneous catalyst was comprehensively characterized using thermogravimetric analysis (TGA), energy dispersive spectroscopy (EDS), scanning electron microscopy (SEM), X-ray diffraction (XRD), vibrating sample magnetometry (VSM), inductively coupled plasma (ICP) atomic absorption spectroscopy, and Fourier transform infrared (FT-IR) spectroscopy. The catalyst demonstrated outstanding catalytic efficiency, achieving a 98% yield in the reduction of nitroarenes and facilitating the synthesis of diaryl sulfide derivatives under green conditions.

This study investigates the electrocatalytic activity of palladium (Pd) nanocatalysts combined with nanoparticles (NPs) of cerium oxide (CeO) polyhedra (Pd/CeO/C poly) and with morphologies of cube (Pd/CeO/C NC), hexagonal sheet (Pd/CeO/C NS), and nanorod (Pd/CeO/C NR) for the formate electrooxidation reaction (FER) in an alkaline medium, a key process in direct formate fuel cells (DFFCs). X-ray diffraction (XRD) patterns indicate that the CeO NP dislocation density follows the decreasing order of Pd/CeO/C NR > Pd/CeO/C NS > Pd/CeO/C NC > Pd/CeO/C poly. This order corresponds to the Pd concentration observed in X-ray photoelectron spectroscopy (XPS) data.

In addition to enhanced fields and possible charge transfer, the concentration of photothermal energy at the nanoscale is a central feature of plasmon-driven photochemistry. It is well known that light energy can be efficiently concentrated in metal nanoparticles to length scales far below the wavelength of light. Here we demonstrate that the energy absorbed by a gold nanoparticle can be further localized within a bimetallic gold-paladium nanoparticle system by the dissipation of energy into the attached palladium satellite nanoparticles.

This study focuses on the synthesis of a novel magnetic interphase palladium catalyst immobilized on pyromellitic dianhydride (PM)-coated magnetic SnFeO nanoparticles. Such surface functionalization of magnetic particles represents a promising strategy to bridge the gap between heterogeneous and homogeneous catalysis methods. The structure, morphology, and physicochemical properties of these particles were thoroughly examined using various analytical techniques, including FT-IR, SEM, XRD, VSM, ICP, and EDS.
