Abstract Pharmaceutical pollutants introduce highly intricate compounds into the environment due to extensive structural and functional alterations resulting in adverse health effects on organisms. Herein, a novel nanocomposite is designed comprising Cu‐doped BiOBr nanoflakes g‐C 3 N 4 form dual absorber based organic‐inorganic electronic interface for photocatalytic degradation of tetracycline (TC). With incorporating Cu compositing with , band gap decreased from 2.74 eV 2.36 BiOBr:Cu/g‐C also light harvesting ability increased. The investigation rate considered factors such as pH, TC concentration, photocatalyst dosage, irradiation time, efficiency 98 % within 60 min. In prepared nanocomposite, photo‐generated electrons can recombine via atoms mediator holes valence their structure position which leads improved electron/hole separation enhanced activity. predominant active species involved process were found be superoxide radicals. Additionally, exhibited excellent stability, retaining 88 its activity after four cycles.

To improve the dielectric performance of anodic alumina film used in aluminum electrolytic capacitors, this study comparatively investigated microstructure and properties oxide obtained through micro-arc oxidation (MAO) conventional (CAO). It is found that from perspective microstructure, internal structure MAO treated has more larger pores than CAO. This was attributed to generation overflow numerous oxygen bubbles within at locations where plasma sparks occurred during process, thus forming pores. Regarding properties, leakage current after treatment significantly reduced compared CAO, with reductions 58%, 56%, 64%, 74% for tested electrolytes Y1-Y4, respectively.
