“…The Raman peaks at 1349 and 1586 cm −1 correspond to the defect-induced D band and characteristic G band of rGO. The D band represents sp3 carbon defects and the G band corresponds to an ordered sp2 carbon network [26][27][28]. This also further proves that rGO is attached to the substrate of the superfine glass fibre.…”

The development of high-performance air filter has become more and more important to public health. However, it has always been very challenging for developing a multifunctional air filter to simultaneously achieve excellent filtration and antibacterial properties. Herein, a versatile air filter was prepared with loading the reduced graphene (rGO) and zinc oxide on the superfine glass fibre (s-GF) with the three-dimensional network structure by in situ sol–gel process followed by calcination, which aims to achieve synergistic high-efficiency air filtration and rapid response to photocatalytic antibacterial properties under visible light. The air filter showed a three-dimensional network structure based on a rGO/ZnO/s-GF multilayer and exhibited the highest catalytic performance by achieving a 95% degradation effect on rhodamine B within 2 h and achieving 100% antibacterial inactivation of the Escherichia coli and Staphylococcus aureus within 4 h under visible light when the weight ratio of rGO in rGO/ZnO is 1.6%. The air filtration efficiency can also be maintained at 99% after loading ZnO and rGO photocatalytic particles. The spectrum of the photoluminescence (PL), UV-Vis diffuse reflectance spectra (DRS) and electron spin resonance (ESR) indicate that the combination of rGO and ZnO on the s-GF can increase the separation of photogenerated carriers and the specific surface area of the air filter, thereby increasing the photocatalytic response and antibacterial properties of the s-GF air filter under visible light in a short time.

“…Studies have reported the utilization of GO-ZnO nanocomposite for photocatalytic degradation of various dyes like basic fuchsin dye [7] and methyl orange under solar irradiation [8]. Reduced GO–ZnO nanocomposites (RGO@ZnO) have also been used for various applications like reusable adsorbent for organic pollutants [9], enhanced photocatalysis using sunlight [10], electrocatalysis and supercapacitor applications [11]. Thus, the risk of exposure of such nanocomposites needs to be evaluated at the level of each nanoparticle individually.…”

“…Reduced graphene oxide (rGO)/ZnO nanocomposite prepared by ultrasonic-assisted solution method has been studied as an electrode material for supercapacitor application. The electrochemical studies showed the increased specific capacitance (312 Fg −1 ) of the composite compared to the pure ZnO (200 Fg −1 ) with improved cycling stability up to 1000 cycles and confirmed its ability as a proper electrode material for supercapacitors [114]. The graphene-zinc oxide thin film was synthesized by the ultrasonic spray pyrolysis process, which attained the maximum specific capacitance (635 F/g) [115].…”

Zinc oxide (ZnO) is used for various purposes because of its special physico-chemical properties, including large band gap, high binding energy of exciton, nontoxicity, high chemical and thermal stability, large piezoelectric constants, and wurtzite crystal structure with various and widespread applications in electronics, optoelectronics, biochemical sensing, biomedical, and energy-saving systems. This review mainly aimed to present the recent improvement in ZnO-based composite materials with utilization in energy storage systems with a specific focus on lithium-ion batteries, dye-sensitized solar cells, and supercapacitors. The first part of this paper looks at the structure and properties of ZnO and then describes some of the most common synthesizing methods of ZnO composites, including electrochemical, chemical, solvo/hydrothermal, and physical deposition methods. Finally, the recent advancement of ZnO-based composite materials applied in energy storage systems was discussed.
