In this report, novel β-AgVO₃ nanowires/TiO₂ nanoparticles heterojunction was synthesized first time using hydrothermal technique and employed for the photocatalytic decomposition of Rhodamine (RhB) dye, simulated dye-bath effluent and colourless compound i.e. ciprofloxacin (at natural pH) under visible light illumination. The prepared composite composed of β-AgVO₃ nanowires over which the nanoparticles of TiO₂ were distributed. The photocatalytic outcomes demonstrated that prepared β-AgVO₃ nanowires/TiO₂ nanoparticles heterojunction showed enhanced (93% degradation) catalytic properties for the decomposition of RhB dye under visible illumination in contrast to bare TiO₂ (43%). Moreover, β-AgVO₃/TiO₂ exhibited 82% decomposition of simulated dye-bath effluent, signifying enough potential for treating industrial wastewater as well. Reactive species trapping experiments exhibited that OH and e⁻ played pivotal role in the decomposition of RhB dye in aqueous phase. About 58% TOC drop in RhB solution (10 mg/L) was accomplished after 120 min of photocatalytic reaction. Further, the detailed mechanism for the decomposition of RhB dye was discussed.

在此报告中，首次使用水热技术合成了新型的β- AgVO ₃纳米线/ TiO ₂纳米异质结，并用于罗丹明（RhB）染料，模拟的染浴废液和无色化合物即环丙沙星（在自然pH下）的光催化分解。在可见光照射下。制备的复合材料由β- AgVO ₃纳米线组成，上面分布着TiO ₂纳米颗粒。光催化结果表明，制备了β- AgVO ₃纳米线/ TiO ₂与裸露的TiO ₂（43％）相比，纳米粒子异质结在可见光下显示出增强的（RhB降解）催化特性，可降解RhB染料。此外，β- AgVO ₃ / TiO ₂表现出82％的模拟染浴废水分解，也表明有足够的潜力处理工业废水。反应性物质捕获实验显示出该OH和e ^-在罗丹明B染料在水相中的分解起到关键作用。120分钟的光催化反应后，RhB溶液（10 mg / L）的TOC下降约58％。此外，讨论了RhB染料分解的详细机理。
