“…The photocatalysis technique is recognized as a cost-effective technology with a sustainable application, which can effectively mineralize toxic pollutants into small molecules with less harm, and the most prominent among them is water purification for the effective removal of antibiotics. − Nevertheless, due to the need of degrading pollutants in complex and harsh environments, higher requirements are put forward for the morphology and function of photocatalysts. − Except for efficient photocatalytic activity, real-time temperature feedback is also required to ensure the safety of photocatalysis. , Therefore, continuous exploration for efficient photocatalytic materials with multiple functions has become the research priority in the future.…”

The problem of water pollution caused by antibiotics urgently needs to be solved urgently. In this study, the Bi5O7I:Er3+-Yb3+ (BOIEY) nanoflowers with a diameter of 600–900 nm loaded flexible fibrous membrane has been synthesized via a combined hydrothermal and electrospinning process. It is noteworthy that the composite fibers successfully achieved efficient catalytic purification under real-time temperature monitoring. The BOIE0.5Y1.5/PAN composite fibers displayed the highest photocatalytic performance in the degradation of tetracycline hydrochloride (TC-HCl), with a removal rate of 91.83% in 80 min, which is 1.76 times that of pure BOI. The efficient photocatalytic performance was mainly attributed to the doping of rare earth ions and the special structure of the composite fibers. Er3+ and Yb3+ ions played the role of broadening the absorption spectrum by upconverting near-infrared light into visible light and promoted the separation of electron and hole pairs, thereby improving the photocatalytic efficiency. In addition, the unique structure of the hollow spherical-flower-loaded flexible fibrous membrane exhibited a larger specific surface area and stronger photon absorption capacity compared with traditional nanocrystals (NCs). Furthermore, based on the 2H11/2/4S3/2 → 4I15/2 radiative transitions of Er3+, the real-time temperature feedback of the degradation process in the 303–433 K ranges is evaluated and the relative temperature sensitivity reaches 0.63% K–1 at 353 K. The dual-function composite fibers provide insight into antibiotic removal in complex environments and ecological restoration.
