Electrochemical mineralization of perfluorooctane sulfonate by novel F and Sb co-doped Ti/SnO 2 electrode containing Sn-Sb interlayer

Recent advances in electrocatalysts for halogenated organic pollutant degradation

“…Components (e.g., F, Ni, Bi, Fe, Ru, Co, Ce, Pd, TiN) often work as co-dopants to improve the performance of Sb-SnO 2 electrode. 65,[69][70][71] Yang et al 65 showed high capacity toward the generation of active oxidants such as chlorine, ozone, and free radicals. 88 Kaur and co-authors 86…”

Oxygen Vacancy as a Medium-Induced Ferromagnetism in (Fe, Sb) Codoped SnO2 Films

“…The Sb 3d core-level spectrum contains double peaks with binding energies of 530.8 and 540.1 eV, respectively, corresponding to Sb 3d 5/2 and Sb 3d 3/2 , as shown in Figure b. However, Sb 3d 3/2 can also be divided into characteristic peaks I and II, implying that Sb is present as mixed valence Sb 5+ and Sb 3+ in the SnO 2 lattice Figure c shows the binding energy spectrum of Fe 2p which can be fitted into four parts: Fe 3+ : (2p 3/2 : 710.2 eV; 2p 1/2 : 724.5 eV), Fe 2+ : (2p 3/2 :708.5 eV; 2p 1/2 :722.3 eV), Fe satellite peaks (715.2, 728.6 eV), and Sn 2p 3/2 :716.7 eV.…”

Facile synthesis of highly active Ti/Sb-SnO2 electrode by sol-gel spinning technique for landfill leachate treatment

“…The diffraction peaks of SnO 2 were observed at 53.143°, 63.298°(JCPDS card 50-1429) and 26.495°, 33.727°(JCPDS card 46-1088). Doping of Sb ions in SnO 2 coating could not be clearly discerned through the XRD spectrum (Yang et al 2017), the reasons might be: 1. The Sb content was too low to be detected by XRD; 2.…”
