“…As a noble transition metal, palladium has fascinated chemists for a variety of reasons, including its exceptional chemical stability and catalytic properties (including the catalytic cross-couplings in organic synthesis famously known as the Suzuki reactions), and has been demonstrated to have important applications as catalytic converters and hydrogen-storage technologies. Palladium is also used in electronics, dentistry, medicine, hydrogen purification, chemical applications, and groundwater treatment. − A number of experimental works have explored the synthesis of Pd architectures on graphene. − However, despite extensive work on the growth of graphene on Ni and Pt (members of the same group as Pd) and a very early demonstration that graphene can be synthesized on palladium surfaces, very little work has been done to explore the nature of large-area graphene synthesis on Pd substrates.…”

We present a detailed investigation of the nucleation sites, growth, and morphology of large-area graphene samples synthesized via chemical vapor deposition (CVD) on bulk palladium substrates. The CVD chamber was systematically controlled over a large range of growth temperatures and durations, and the nature of graphene growth under these conditions was thoroughly investigated using a combination of scanning electron microscopy and a statistical analysis of >500 Raman spectra. Graphene growth was found to initiate at ∼825 °C, above which the growth rate increased rapidly. At T = 1000 °C, defect-free high-quality graphene was found to grow at an unprecedented rate of tens of micrometers per second, orders of magnitude faster than past reports on Cu- or Ni-based growth, thus leading to macroscopic coverage of the substrate within seconds of growth initiation. By arresting the growth at lower temperatures, we found that graphene nanoislands preferred to nucleate at very specific positions close to terrace edges and step inner edges. Evidence of both epitaxial and self-limiting growth was found. Along with monolayer graphene, both Bernal and turbostratic multilayer graphene could be obtained. A detailed evolution of the different types of graphene, as a function of both growth temperature and duration, has been presented. From these, optimal growth conditions for any chosen type of graphene sample can be inferred.

“…The electrodeposited layer is similar in appearance to previous reports of Pd nanoparticle modified ITO formed either by seed-growth 36 or electrodeposition in an organic solvent. 37 The density of Pd particles on the low coverage surface clearly lies below the percolation threshold. The density of the smaller Pd structures in the layer is markedly larger for Q = 32 mC cm À2 whereas the number and size of the larger aggregates remain approximately unchanged.…”

The present work reports the design, synthesis, and characterization of palladium complex immobilized on chitosan/poly(o-phenylenediamine) (CS-PoPD-Pd) for the catalytic application in the Suzuki-Miyaura C C cross-coupling reaction through a nontoxic, inexpensive, eco-friendly, and practical method. Fourier-transform-infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), elemental mapping, X-ray diffraction (XRD), and inductively coupled plasma-optical emission spectrometry (ICP-OES) techniques were used for analyzing the prepared catalyst.Characterization studies showed that CS-PoPD-Pd was successfully synthesized according to our design. CS-PoPD-Pd composite demonstrated high product yield and high turnover number (TON) and turnover frequency (TOF) values with small catalyst loading for the Suzuki-Miyaura C C cross-coupling reaction under mild reaction conditions. Besides, the synthesized CS-PoPD-Pd composite could be readily recycled and reused for at least five runs without discernible loss of its catalytic activity.
