Environmental Technology, Год журнала: 2025, Номер unknown, С. 1 - 18

Опубликована: Фев. 2, 2025

This study investigates the use of porous structured carbon felt (CF) as a substrate for preparation lead dioxide (CF/PbO2) anode electrochemical oxidation Rhodamine B (RhB). Compared to traditional titanium-based (Ti/PbO2) and graphite sheet-based (GS/PbO2) anodes, CF/PbO2 exhibited superior electrocatalytic activity, achieving RhB degradation efficiency exceeding 99%. After 10 cycles, activity remained robust, with over 97%. Fluorescence spectroscopy, quenching experiments, tests indicate that behaviour on GS/PbO2 anodes was governed by direct electron transfer, while indirect via •HO radicals pivotal Ti/PbO2 anode. LC-MS analysis identified intermediates degradation, contributing proposed pathway. provides an efficient organic pollutants in water.

Abstract A novel phosphorus‐doped graphitic carbon nitride nanosheets (PS‐CN) photocatalyst was prepared by thermal polycondensation and stripping method, its physicochemical properties were characterized. The results show that PS‐CN formed a thin sheet multi‐cavity structure delamination could enhance the surface area, light reception, adsorption capacity. activated sodium percarbonate system (PS‐CN/SPC) developed for degradation of dyeing wastewater with methylene blue (MB) as target pollutant mechanism analyzed. At room temperature (20 °C), rate MB in PS‐CN/SPC within 10 min (88.13 %) three times pure g‐C 3 N 4 . In addition, completely degraded under visible 60 min. Moreover, exhibited excellent reusability rates have remained above 96 % five consecutive cycles. free radical quenching experiments showed hole (h + ), hydroxyl (•OH) superoxide (•O 2 − ) all participated degradation, •OH main active species. would provide high‐value solution treatment dye due to low cost raw materials, superior photocatalytic activity, simple synthesis catalyst.
