“…Fiber geometry analysis showed that composites with a smaller fiberglass diameter have better fatigue and processing properties. Assessment of the impact of the size and type of reinforcement is very important because it finds reference in almost every examined material property, e.g., mechanical, thermal, tribological, optical, and chemical properties, which are well known in many works in the field of polymer composites as well as metal and ceramic composites [46,47].…”

The paper evaluated the possibility of potential reinforcing of poly(oxymethylene) (POM) by glass fiber and the influence of fiberglass addition on mechanical properties under dynamic load. Four types of composites with glass fiber and another four with carbon fiber were produced. The fiber content ranged from 5% to 40% by weight. In the experimental part, the basic mechanical and fatigue properties of POM-based composites were determined. The impact of water absorption was also investigated. The influence of fiber geometry on the mechanical behavior of fiber-reinforced composites of various diameters was determined. To refer to the effects of reinforcement and determine the features of the structure scanning electron microscopy images were taken. The results showed that the addition of up to 10 wt %. fiberglass increases the tensile properties and impact strength more than twice, the ability to absorb energy also increases in relation to neat poly(oxymethylene). Fiber geometry also has a significant impact on the mechanical properties. The study of the mechanical properties at dynamic loads over time suggests that composites filled with a smaller fiber diameter have better fatigue properties.as well as heating fabrics powered by electricity [2][3][4][5]. Many scientific papers present the advantages of introducing carbon fibers to thermoplastic materials. Carbon fibers are not only lightweight or provide very good strength properties, but also have a positive effect on tribological properties, and therefore they also can be successfully used as a reinforcement in ceramic matrices [6][7][8][9][10][11][12][13][14][15][16][17].Carbon fibers are not only one fiber introduced in composites which provide good mechanical properties. Currently, about 60% of produced glass fibers are applied to make composites on polymeric matrices, even though they have insignificantly lower physical and mechanical properties than carbon fibers. Glass fibers are characterized by low elongation and high modulus of elasticity. Attention should be paid to good dielectric properties, namely the fibers have low values of relative permittivity and dielectric loss factor. A valuable advantage of glass fibers is the very good wettability of the polymers, and hence the possibility of forming a strong bond at the polymer/glass interface. The mechanical properties of fiber-reinforced composites improve as the length of reinforcing fibers increase, while the strength of a single glass fiber depends on its diameter. If the fiber diameter is larger, there is a higher probability of material defects and damages describe in literature as micronotches and microcracks [18].Many groups of researchers conduct research on polymer composites with glass fiber. It has been revealed that glass fibers successfully strengthen polymers causing better strength properties, higher resistance to creep, and fatigue, as well as provide greater dimensional stability [19][20][21][22].POM is a thermoplastic material with a high degree of crystallinity. This polymer is obta...

“…It is noteworthy that only 4% of solar light is placed in the UV region, while nearly 46% of its spectrum is placed in the visible region which is far abundant. Hence, developing a robust solar-responsive photocatalyst is urgently required for the next-generation of photocatalysts [16][17][18][19][20][21][22][23] .…”

Transition metal sulfide semiconductors have achieved significant attention in the field of photocatalysis and degradation of pollutants. MoS 2 with a two dimensional (2D) layered structure, a narrow bandgap and the ability of getting excited while being exposed to visible light, has demonstrated great potential in visible-light-driven photocatalysts. However, it possesses fast-paced recombination of charges. in this study, the coupled MoS 2 nanosheets were synthesized with Zno nanorods to develop the heterojunctions photocatalyst in order to obtain superior photoactivity. the charge transfer in this composite is not adequate to achieve desirable activity. therefore, heterojunction was modified by reduced graphene oxide (RGO) nanosheets and carbon nanotubes (cnts) to develop the RGo/Zno/MoS 2 and cnts/Zno/MoS 2 ternary nanocomposites. the structure, morphology, composition, optical and photocatalytic properties of the as-fabricated samples were characterized through X-ray diffraction (XRD), Fourier Transform Infrared (FTIR), Field Emission Scanning electron Microscopy (feSeM), transmission electron Microscopy (teM), energy-Dispersive X-ray (eDX), elemental mapping, photoluminescence (pL), Ultraviolet-Visible spectroscopy (UV-ViS), and Brunauer-emmett-teller (Bet) techniques. the photo-catalytic performance of all samples was evaluated through photodegradation of aniline in aqueous solution. the combination of RGo or cnts into the Zno/MoS 2 greatly promoted the catalytic activity. However, the resulting RGo/Zno/MoS 2 ternary nanocomposites showed appreciably increased catalytic performance, faster than that of cnts/Zno/MoS 2. charge carrier transfer studies, the Bet surface area analysis, and the optical studies confirmed this superiority. The role of operational variables namely, solution pH, catalyst dosage amount, and initial concentration of aniline was then investigated for obtaining maximum degradation. complete degradation was observed, in the case of pH = 4, catalyst dosage of 0.7 g/L and aniline concentration of 80 ppm, and light intensity of 100 W. According to the results of trapping experiments, hydroxyl radical was found to be the main active species in the photocatalytic reaction. Meanwhile, a plausible mechanism was proposed for describing the degradation of aniline upon ternary composite. Moreover, the catalyst showed excellent reusability and stability after five consecutive cycles due to the synergistic effect between its components. Total-Organic-Carbon concentration (TOC) results suggested that complete mineralization of aniline occurred after 210 min of irradiation. Finally, a real petrochemical wastewater sample was evaluated for testing the catalytic ability of the as-fabricated composites in real case studies and it was observed that the process successfully quenched 100% and 93% of Chemical Oxygen Demand (COD) and TOC in the wastewater, respectively.

“…Furthermore, Hu et.al reported that the novel ternary heterogeneous BiOCl/TiO 2 /sepiolite composite synthesized via the hydrolysis precipitation method shows enhanced photocatalytic activity due to the synergistic effect within the BiOCl/TiO 2 /sepiolite ternary heterogeneous system. This system exhibited superior adsorption, visible‐light response performance and efficientseparation of the photogenerated electron‐hole pairs . Recently, Li et.al investigated that a novel BiOCl/TiO 2 hierarchical composite synthesized by one‐pot solvothermal synthesis with the aid of poly vinyl pyrrolidone (PVP) exhibits superior visible‐light response, enhanced photoactivity and photostability for the formation of the BiOCl/TiO 2 heterojunctions and rate constant of the photocatalyst can reach about 0.1510 min −1 is far more superior than commercial P25, as‐prepared anatase TiO 2 nanoparticles and tetragonal BiOCl alone .…”

TiO₂ Nanoparticles Decorated on BiOCl Flakes with Enhanced Visible Light Photocatalytic Activity

et al. 2020

Facile preparation route for BiOCl and BiOCl/TiO2 nanocomposites with TiO2 nanoparticles decorated on BiOCl flakes via solution combustion method is reported in the present paper. Structural, textural and optical properties of the prepared materials are extensively studied using various physicochemical characterization tools such as X‐ray diffraction (XRD), field‐emission scanning electron microscopy (FE‐SEM), transmission electron microscopy (TEM), UV‐vis spectroscopy (DRS), N2 adsorption‐desorption study (BET), photoluminescence spectroscopy (PL), etc. BiOCl/TiO2 nanocomposites show a red shift in the light absorption as compared to that of bare BiOCl which leads to the extended absorption in visible light region. Further photocatalytic experiments for Rhodamine B and phenol degradation demonstrate that the BiOCl/TiO2 nanocomposites have superior photocatalytic properties than bare BiOCl. Improved photocatalytic performance of BiOCl/TiO2 composites is attributed to the synergistic effect between BiOCl flakes and TiO2 nanoparticles, extended visible light absorption and delayed charge recombination.
