Preparation and characterization of multifunctional nanofibers containing metal–organic frameworks and Cu₂O nanoparticles: particulate matter capture and antibacterial activity

Abstract

Protection from particulate matter (PM10 and PM2.5) and microorganisms using MOFs (metal–organic frameworks) and nanoparticles used in filtration has been a major challenge.

Enhanced adsorption and synergistic photocatalytic degradation of tetracycline by MOF-801/GO composites via solvothermal synthesis

“…In general, MOF-801 is generally used to enhance the photocatalytic properties by preparing composites with semiconductors and noble metals. 13,32,33 There are few reports on the improvement of the adsorption and photocatalytic efficiency of MOF-801, and its application in the adsorption and synergistic photocatalytic degradation of antibiotics.…”

Poly(vinylidene fluoride) ultrafiltration membranes tailored with zirconium‐based MOF‐801 for water treatment applications

“…Besides, the two sharp peaks at 661 and 485 cm −1 are assigned to vibrations of Zr OH and asymmetric stretching of the Zr O C group of MOF-801. 25,26 The crystalline nature of MOF-801 is investigated by powder XRD as shown in Fig. 2(b).…”

“…The peaks at 983 and 799 cm −1 are attributed to CH 3 skeletal vibrations and C=CH out‐of‐plane bending. Besides, the two sharp peaks at 661 and 485 cm −1 are assigned to vibrations of ZrOH and asymmetric stretching of the ZrOC group of MOF‐801 25,26 …”

Bimetallic oxide Cu2O@MnO2 with exposed phase interfaces for dual-effect purification of indoor formaldehyde and pathogenic bacteria

“…In general, compared with the pure catalyst MnO 2 and bacteriostatic agent Cu 2 O, bimetallic oxide Cu 2 O@MnO 2 with exposed phase interfaces respectively shows superior HCHO removal efficiency and pathogen inactivation ability, which could be attributed to the following two factors. On the one hand, the modification of MnO 2 by Cu 2 O particles induces the generation of reactive oxygen species via the separated electron–hole pairs under the assistance of visible light for the oxidative degradation of HCHO and inactivation of bacterial DNA double strands, achieving the double-effect purification of chemical and biological indoor pollutants by an Mn-based composite; 52,53 on the other hand, the bimetallic oxide Cu 2 O@MnO 2 with exposed phase interfaces improves the migration of lattice oxygen and the adsorption–activation of O 2 on the surface of materials to generate more reactive oxygen species for the degradation of HCHO and pathogenic bacteria. 54 In conclusion, this work effectively provides innovative ideas and exploration experience for the construction of composite materials with exposed phase interfaces and the design of multifunctional purification materials for indoor chemical and biological indoor environmental pollutants.…”
