TiO-ZnO functionalized low-cost ceramic membranes from coal fly ash for the removal of tetracycline from water under visible light.

Hybrid wastewater treatment systems offer viable solutions to enhance the removal of complicated contaminants from aqueous system. This innovation has opened new avenues for advanced wastewater treatment processes. Herein, a novel TiO-ZnO functionalized coal fly ash-based ceramic membrane was fabricated by utilizing a combined pressing and sintering method.

Photocatalytic degradation of tetracycline using surface defective black TiO-ZnO heterojunction photocatalyst under visible light.

Fabrication of heterojunction and surface defective engineering, through the formation of oxygen vacancies, are among the various photocatalytic enhancement techniques. A combination of these techniques has the prospect of enhancing photocatalytic activities through improved light absorption capabilities and charge separation process of the photocatalysts. In this study, a heterojunction of black titanium oxide-zinc oxide (BTiO-ZnO) nanocomposite was synthesized using the conventional sol-gel approach, coupled with aluminum foil-assisted NaBH reduction.
