Summary: This study aimed to evaluate the direct oxidation of a cefalexin antibiotic solution using a new generation Sn/Sb/Ni anode. Experimental results showed that electrochemical oxidation with this anode achieved complete removal of COD and TOC in a short period of time. The stability of the Sn/Sb/Ni anode was also observed, with minimal change after 300 hours of electrolysis. Compared to other studies in the literature, this method showed rapid mineralization and did not require pH adjustment.

Summary: This study synthesized Ta(V)-doped SnO2 (TTO) electrocatalysts as alternative to Sb-doped SnO2 (ATO) and found that the optimized TTO exhibits higher activity for the decomposition of phenol in certain solutions compared to ATO, but is less stable. Characterizations revealed a larger production of reactive oxygen species with ATO and reactive chlorine species with TTO.

Summary: This study doped Mn into Ti/SnO2-Sb electrodes and found that the doped electrodes exhibited better electrochemical performance. The experiment also showed that the molar ratio of Sn:Sb:Mn and the number of coating layers influenced the electrochemical performance. Under the optimal conditions, the Mn-doped electrode achieved a high decolorization rate of dye wastewater at a low cell voltage.

Summary: Tin dioxide (SnO2) is a commonly used semiconductor for gas sensing applications, but its lack of selectivity and sensitivity to humidity limit its potential usage. This study focused on highly doped SnO2:Sb and found that it exhibits high selectivity to NO2 with good sensitivity and limited influence from humidity.

Summary: Ni, Zn, and Co-doped Ti/SnO2-Sb anodes were prepared using an unconventional sol-gel method and used for phenol electrochemical degradation. Among them, Ti/SnO2-Sb-Co showed the longest service life (213.9 h), lowest energy consumption, and promising practical application potential, despite a slightly lower phenol degradation rate compared to Ti/SnO2-Sb-Ni and Ti/SnO2-Sb-Zn.

Summary: The study found that ATO hollow submicron spheres rely on better particle dispersion, lower thermal conductivity, higher specific heat capacity, and higher infrared emissivity for thermal insulation. The 50 nm ATO absorbed the least solar heat but reflected the most light, while 100 nm ATO showed the opposite behavior.

Summary: This study investigated the effect of Bi metal doping on the Ti/SnO2-Sb/PbO2 anode and found that Bi5+ doping increased the active sites on the electrode surface, resulting in higher catalytic reaction activity and oxygen evolution potential. Electrocatalytic oxidation experiments demonstrated that the Ti/SnO2-Sb/Bi5+-PbO2 electrode exhibited high removal rate and apparent kinetic coefficient for phenol. Energy consumption evaluation showed that Bi5+-doped electrodes had the highest current efficiency and lowest energy consumption.

Summary: Electrocatalysis is widely used for treating organic compounds in wastewater, but efficiently oxidizing gaseous organic compounds remains challenging. In this study, a Nafion-modified SnO2-Sb/Ti anode was fabricated and assembled into a solid-state reactor, achieving highly efficient electrooxidation of gaseous toluene. The Nafion-coated anode mineralized over 85% of toluene with >97% CO2 selectivity in 90 minutes at ambient temperature, compared to only 8% conversion over the bare anode under the same conditions. Nafion modification increased the electrochemical active surface area (ECSA), improved charge transfer, and enhanced surface hydrophobicity.

Summary: Pd-modified Sb-doped SnO2 nanomaterials were prepared using a hydrothermal reaction and reduction method. The samples exhibited uniform doping of Sb within the SnO2 lattice and successful incorporation of Pd on the surface. Compared to pristine SnO2, the material with 3 mol% Sb doping and 7 wt% Pd decoration showed the highest response to hydrogen gas at high temperature, as well as excellent selectivity and cycling stability. The improved sensing performance was attributed to changes in the energy band structure, lattice distortion-induced oxygen vacancies, and strong metal-support interaction between Pd and SnO2.
