The applications of copper (Cu) and Cu-based nanoparticles, which are based on the earth-abundant and inexpensive copper metal, have generated a great deal of interest in recent years, especially in the field of catalysis. The possible modification of the chemical and physical properties of these nanoparticles using different synthetic strategies and conditions and/or via postsynthetic chemical treatments has been largely responsible for the rapid growth of interest in these nanomaterials and their applications in catalysis. In addition, the design and development of novel support and/or multimetallic systems (e.g., alloys, etc.) has also made significant contributions to the field. In this comprehensive review, we report different synthetic approaches to Cu and Cu-based nanoparticles (metallic copper, copper oxides, and hybrid copper nanostructures) and copper nanoparticles immobilized into or supported on various support materials (SiO2, magnetic support materials, etc.), along with their applications i...

Nanocarbons for the Development of Advanced Catalysts

Chemical state X-ray photoelectron spectroscopic analysis of copper species is challenging because of the complexity of the 2p spectra resulting from shake-up structures for Cu(II) species and overlapping binding energies for Cu metal and Cu(I) species. This paper builds upon and extends previously published X-ray photoelectron spectroscopy curve-fitting and data analysis procedures for a wide range of copper containing species. Steps undertaken include the following: (i) an examination of existing Cu 2p3/2 main peak and Cu 2p3/2 – Cu L3M4,5M4,5 Auger parameter literature data, (ii) analysis of a series of quality standard samples, (iii) curve-fitting procedures for both the Cu 2p3/2 and the Cu L3M4,5M4,5 spectra (as well as associated anions), (iv) calculations that determine the amount of Cu(II) species in a mixed oxidation state system, (v) calculations and necessary data for thin film mixed oxide/hydroxide thickness measurements, and (vi) a presentation of literature and standard sample values in a Wagner (chemical state) plot.

The spin- and orbital-moment magnetization form factors in NiO have been measured using magnetic x-ray scattering. The polarization analysis of nonresonant magnetic-scattering intensities has evidenced a large contribution from the orbital moment to the total magnetization. In the antiferromagnetic phase, the orbital moment contributes $17\ifmmode\pm\else\textpm\fi{}3%$ to the magnetization density.

Observation of orbital moment in NiO

Among diatoms, Phaeodactylum tricornutum is a peculiar species that exists in three morphotypes with distinct cell wall structures and low silica context. X-ray photoelectron spectroscopy (XPS) analysis was performed on P. tricornutum and compared with diatom Thalassiosira pseudonana, the result provide new information on the chemical composition (elements, chemical functions, classes of biochemical compounds) of the cell surface. Two types of silicon were found condensed-silica (SiO2) and weakly polymerised silicate. Cells of T. pseudonana showed the highest concentration of silicon, with a majority in the form of condensed silica. For the fusiform and triradiate morpotypes of P. tricornutum, the majority of the small concentration of silican found was in the form of weakly polymerised silica. for all morphotypes of P. tricornutum, higher polysaccharide concentrations replaced silicas as a structural part of the cell wall. In both diatoms a high concentration of lipids was measured, in the form of carboxylic esters. Protonated nitrogen and phosphate were found in correlated amounts and attributed not only to phospholipids but also to phosphoproteins. Chloride ions characterised by a high electron density might be associated to the moieties. Sulfate groups were also detected, principally in P. tricornutum, and attributed to monoesters of polysaccharides.
