“…This observed decreasing trend of bandgaps is in good agreement with the previous reports of narrower bandgaps for nanostructured (2.23 eV for nanosheets and 2.70 eV for nanotubes) and bulk (∼1.30 eV) MnO 2 materials. [73][74][75][76] The bandgaps of the composites therefore represented an average of the values of the two materials. 25,77,78 Concerning the annealing composites, the bandgap of the annealed Ga particles was 4.37 eV, which increased closer to the value of pure Ga 2 O 3 (∼4.47 eV).…”

“…Second, the transformation of NIR light into Vis and UV light mediated by UCNPs through the FRET process enables ZIF-8 and MnO 2 to generate ROS. Moreover, MnO 2 exhibits the ability to induce fatal responses in pathogenic bacteria by disrupting cell structures and modulating the activity of nucleic acids and proteins through interactions, 55,56 therefore impacting enzymatic activity and resulting in pathogenic bacterial death.…”

In the field of environmental science, efficient removal of organic pollutants and pathogenic bacteria from wastewater using a photocatalytic process that responds to the full spectrum of sunlight is crucial. In this study, a highly effective nanoheterojunction called NaGdF4:Yb,Er@zeolitic imidazolate framework‐8/manganese dioxide (NaGdF4:Yb,Er@ZIF‐8/MnO2, UCZM) was synthesized. This nanoheterojunction exhibits a remarkable ability to respond to the entire range of ultraviolet, visible, and infrared light. Under simulated sunlight, UCZM demonstrated outstanding performance in degrading malachite green dye, with a degradation efficiency of 92.6% within 90 min. Moreover, UCZM completely inactivated both Staphylococcus aureus and Escherichia coli within 20 min under simulated sunlight. Mechanistic studies revealed that NaGdF4:Yb,Er played a crucial role in activating ZIF‐8 and MnO2 through Förster resonance energy transfer, facilitating the photocatalytic process. The formation of a Z‐type heterojunction in UCZM promoted the efficient separation of photogenerated carriers. Furthermore, UCZM exhibited excellent biosafety properties. This study represents the first exploration of a composite material composed of UCNPs, ZIF‐8, and MnO2 for photocatalytic applications. The findings highlight the potential of this novel nanoheterojunction design, which exhibits a full spectral response, for tackling water pollution through efficient photocatalytic degradation of organic pollutants and inactivation of pathogenic bacteria.image
