Tailoring the physical and chemical properties of Sn_1−xCo_xO₂ nanoparticles: an experimental and theoretical approach

Abstract

In this work, we present a coupled experimental and theoretical first-principles investigation on one of the more promising oxide-diluted magnetic semiconductors, the Sn1−xCoxO2 nanoparticle system, in order to see the effect of cobalt doping on the physical and chemical properties.

A simple in situ deposition of metal alloys on graphite surface based on Sb, Bi, Cu, and Sn as an electrocatalyst for V 3 + / V 2 + redox reaction

“… 40‐42 The Sn spectrum displays two peaks at 495.6 eV (Sn 3d 3/2 ) and 484.9 eV (Sn 3d 5/2 ) for Sn 0. 10,43,44 Eventually, the XPS results are clear evidence of the electrodeposition of metal ions on the electrode surface, compatible with the obtained EDX results.…”

Copper cobalt tin sulphide (Cu2CoSnS4) anodes synthesised using a chemical route for stable and efficient rechargeable lithium-ion batteries

“…3(c)) displays peaks at 486.05 eV (3d 5/2) and 494.6 eV (3d 3/2) that are associated with Sn 2+ whereas the peaks at 487.03 eV (3d 5/2) and 495.3 eV (3d 3/2) are due to Sn 4+ oxidation states. 36 The S 2p spectrum shown in Fig. 3(d) showed four peaks, two of which are located at 161.64 eV (2p 3/2 ) and 162.9 eV (2p 1/2 ), and are due to the sulphide phase.…”

“…5c), the peaks at 485.9 and 494.6 eV observed in the original sample disappear in the charged and discharged states, suggesting the formation of irreversible Sn 4+ (487.1 and 495.6 eV) states in the sample. 36 The S 2p spectra (Fig. 5d) of the original sample show peaks at 161.6 and 162.7 eV, which disappear in the discharged and charged states, and a broad peak at 169.7 appears, which is due to the sulphonate that forms due to the reaction between Li 2+ and trace amounts of oxygen and water.…”

Tuning the magnetic properties of Sn1−x−yCe4+xCe3+yO2 nanoparticles: an experimental and theoretical approach

“…We performed ab initio simulations of Ce-doped SnO 2 to provide an atomistic understanding of the ingredients that determine the oxidation state of the Ce-ions. In our calculations, we adopted a rutile-like SnO 2 structure with a 3 Â 3 Â 3 supercell, 44 containing 54 and 108 atoms of Sn and O, respectively, in its pristine form. Thus, we created a variety of point defects inside it.…”
