Recently, owing to the prevalence of epidemic and pandemic viral diseases, widespread use antiviral drugs (ATVs) such as chloroquine phosphate (CQ) lamivudine (3TC) has raised environmental concerns regarding their presence in wastewater. In this study, we explore our previously developed Bi2O3-doped TiO2 composites supported by powdered activated carbon (Bi2O3–TiO2/PAC; BT/C) catalysts for degrading CQ 3TC a green efficient approach. Under suitable conditions (C0[ATV] = 10 mg/L, pH 7, catalyst dose 250 mg/L), degradation rates reached 95.1% 57.1% after radiation 30 120 min, respectively. situ irradiation X-ray photoelectron spectroscopy results density functional theory simulations confirmed that BT/C enhanced interfacial electron transfer from Bi2O3 suppressed carrier recombination. Quenching experiments paramagnetic resonance ·O2– generation, leading subsequent ·OH 1O2 production. addition, pathways were proposed. Toxicity assessments indicated reduced overall toxicity during photocatalysis. proved effective across diverse water qualities maintained stable performance through repeated use. This study offers new insights into photocatalytic ATV-removal mechanisms opens avenues innovative hybrid treatment technologies.

The structural modulation of pristine graphitic carbon nitride poses a considerable challenge in the rational design catalysts for efficient degradation small organic pollutants under visible light. In this study, we combined first-principles calculations and structure-function relationship to predict high-performance catalyst. results reveal that CN-8 demonstrates remarkable degree electron-hole separation. Notably, shows exceptional efficiency towards rhodamine B, tetracycline, bisphenol A, fluralaner light irradiation. Specifically, rate constants are 11, 4, 12, 32 times higher, respectively, compared bulk g-C3N4. Through density functional theory investigations relationship, it is confirmed superior catalytic activity lies modifying amino position, which alters electron cloud distribution promotes separation photo-generated pairs. This study provides valuable insights development eco-friendly photocatalysts environmental remediation.
