Sažetak:	Title screen Ag nanoparticle-decorated Bi2O3-TiO2 heterogeneous photocatalysts were successfully obtained by combining facile sacrificial templates and photoreduction. The as-synthesized Ag@Bi2O3-TiO2 photocatalysts with a narrow band gap of 2.40 eV exhibited considerable photocatalytic activity to degrade rhodamine B (RhB) and tetracycline hydrochloride (TCH), and the removal efficiency reached 100% and 92%, respectively. Ag@Bi2O3-TiO2 photocatalysts also exhibited stable recyclability for the degradation of RhB and TCH. Trapping experiments helped determine the major reactive oxidative species for TCH photodegradation. The desirable photodegradation performance is mainly attributed to improved light absorption, enhanced charge separation, and strong redox capacity of Ag@Bi2O3-TiO2 nanostructures with S-scheme heterojunction. This work provides a facile avenue to construct heterogeneous tubular nanostructures with intensive photoabsorbance and effective photocatalysis to degrade organic contaminants.
