Nanoscale palladium clusters in the form of parallel strips have been formed on the surface of graphite with the help of a surface micellar template of cetyltrimethylammonium bromide using a chemical deposition method. The repeat period of the palladium strips deposited at 25 °C is 65 nm, with a width of 40 nm and height of 2 nm. The elemental composition of the metal clusters was confirmed using X-ray fluorescence analysis and TEM-EDX. The fact that the strips are composed of metallic palladium was also confirmed by testing the membrane electrode assembly with the strips in a commercial fuel cell. Using the obtained micellar template, the radius of the curvature of the AFM probe tip was estimated with the help of a unique method. The radius is equal to 10 nm and matches the value provided by the manufacturer. [ABSTRACT FROM AUTHOR]

reaction of bis(triphenylphosphine)palladium dibromide with white phosphorus in the presence of NaBPh selectively gives phosphorous acid HPO. The mechanism of the formation involves coordination of a white phosphorus molecule, ligand exchange, and hydrolysis of the coordinated P molecule in the coordination sphere of palladium.

In situ generated palladium nanoparticles stabilized by a sterically hindered phosphonium salt are shown to act as an efficient catalyst for the Suzuki cross-coupling reaction of haloarenes with arylboronic acids. [ABSTRACT FROM AUTHOR]
