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: 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: In this study, a self-standing PAN-based SnO2/Sb/CFs anodic membrane was fabricated by incorporating SnO2/Sb nanoparticles into carbon nanofibrous (CFs) membrane to treat sulfamethoxazole (SMX), an emerging refractory antibiotic pollutant. The SnO2/Sb/CFs nanofibrous anodic membrane showed excellent SMX degradation capacity due to the adsorption ability of CFs and the enhanced electrooxidation capacity by SnO2/Sb. It also showed improved mass transfer rate and degradation performance compared to conventional plate electrodes.
