| Abstract: | The development of multifunctional nanomaterials for the remediation of complex wastewater is increasingly urgent. Based on this, the current study focused on optimizing decontamination and disinfection of a simulated wastewater via heterogeneous photocatalysis using Ca2+/Mg2+ codoped ZnO nano-semiconductors (ZnO-CaMg x%, with x = 0; 1.0; 3.0; 5.0; 7.0 mol%), synthesized by a modified sol-gel method. These nano-semiconductors exhibited improved properties over undoped ZnO, including smaller crystallite size, higher specific area and increased structural defects with the insertion of Ca2+/Mg2+ codopants. Notably, ZnO-CaMg 3.0 % showed the best performance, degrading ∼90 % of methyl orange (MO) dye and 99 % of chlorpyrifos (CPF) pesticide, in single systems under UV–vis irradiation (240 min, pH 9.0), while undoped ZnO (ZnO-CaMg 0 %) degraded only 56 % and 73 %, respectively. In MO/CPF binary system, ZnO-CaMg 3.0 % photodegraded ∼99 % of both pollutants (λ = 229 nm) after 600 min of UV–vis irradiation. The main reactive species involved in the photocatalytic process were identified, and quality parameters evidenced the efficient mineralization of the pollutants. ZnO-CaMg 3.0 % also exhibited excellent recyclability, degrading 80 % of MO and 99 % of CPF after five photocatalytic cycles in single or binary system. Additionally, these nano-semiconductors exhibited efficient bacteriostatic activity against the harmful pathogens Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). Against S. aureus, MIC values for ZnO-CaMg 0 % and 3.0 % reduced from 1.0 mg mL−1 to 0.12 mg mL−1 after 1 h of visible irradiation. For E. coli , ZnO-CaMg 3.0 % was more effective in the absence of light, but only ZnO-CaMg 0 % showed photo-modulated antibacterial action, reducing MIC from 1.0 mg mL−1 to 0.5 mg mL−1 after 1 h under light incidence. These findings highlight ZnO-CaMg 3.0 % as a promising environmental agent for simultaneous decontamination and disinfection of real wastewater, reducing costs and treatment steps. [Display omitted] • Codoped ZnO-CaMg were synthesized by an eco-friendly sol-gel method. • ZnO-CaMg 3.0 % showed more suitable structural, optical and photocatalytic properties. • ZnO-CaMg 3.0 % photodegraded about 80 % of MO and 99 % of CPF in the binary mixture. • The photocatalytic process promoted the mineralization of MO dye and CPF pesticide. • ZnO-CaMg 3.0 % exhibited a photo-modulated bacteriostatic effect against S. Aureus and E. coli. [ABSTRACT FROM AUTHOR] |
