“…Among these related investigations, the synthesis of nanocatalysts, especially the supported noble metal nanocatalysts, has attracted much attention [1][2][3][4][5]. Several approaches to the preparation of this kind of nanocatalysts have been reported, including conventional impregnation, coprecipitation (CP) and deposition-precipitation (DP) techniques, photodepositon, sputtering, colloidal methods, and so on [9][10][11][12][13][14]. It has been demonstrated that the synthesis of highly dispersed small metal particles is very sensitive towards the synthetic methods.…”

“…This technology excludes contamination of the catalyst and opens up the possibility for controlling the size of the resulting metal particles in the nanometer range [40]. Thus, magnetron sputtering was used to prepare disperse catalysts on the basis of platinum particles 3.5 nm and smaller in size, deposited on different substrates [41][42][43]. The catalytic material in [44] was obtained by sputtering a gold target.…”

Objectives and achievements of the production of disperse composite materials (DCMs) which consist of particles with a metal coating are represented. The prospects of the DCM production by the dusty plasma method based on confining a cloud of micron-sized particles in a discharge plasma and on magnetron sputtering are shown. The method was tested in the preparation of catalyst materials, a superhard diamond polycrystalline material, and a polyquasicrystalline material with a low friction coefficient. The results of investigations of the structure and properties of powdered and sintered DCMs are presented.

“…In those investigations, the focus was to investigate the growth mechanisms, interfacial properties, and the surface evolution of the metal’s electronic states. ,,− Other studies of thin Cu films deposited via PVD probed the properties of the Cu/MgO interface. − These earlier investigations of the Cu/MgO, ,, as well as other systems, ,, are of fundamental importance because they provide information about the catalyst–metal oxide support interactions and its role in heterogeneous catalysis. While some examples of PVD-based deposition studies on metal oxides have been reported previously, , a new deposition method for the Cu/MgO system is described below and serves as the platform for a comprehensive, fundamental study of the physicochemical properties of metal-decorated, structurally well-defined metal oxide nanomaterials.…”

A novel physical vapor-based method was developed to deposit individual atoms and small metal clusters on nanometer scale metal oxide materials without using solvents. It consists of a chamber equipped with a magnetron sputtering gun and a rotating device designed to create a cascade of the nanoparticles and expose them to the metallic beam multiple times. This study investigates the deposition of copper on the surface of high-purity, single (100) facet exposure MgO nanocubes. Using this method retains the high purity and quality of the original MgO (cubic) powders. The properties of the as-deposited Cu/MgO-decorated materials were studied by using both structural and optoelectronic methods (X-ray diffraction, photoluminescence, diffuse reflectance spectroscopy, and electron microscopy) and magnetic susceptibility. Structural and optical measurements reveal evidence that a new composite nanomaterial with identifiable crystalline (Cu, Cu2O, and CuO) and associated electronic properties is produced. Microscopic evidence using Z-contrast STEM images of the MgO surfaces show the presence of Cu species both on the (100) surfaces and on the edges of the cubic particles. Magnetic susceptibility measurements reveal a previously unreported behavior of the Cu-decorated materials unique to the nanometer length scale and the interaction of Cu with the MgO surface.
