“…From Figure 2 a, it is seen that in both cases, sharp peak at 2 θ ≈43.3° and 50° appears for the Cu foil. [ 38,39 ] The magnified view of the peaks presents in MoS 2 , and MoS 2 @ZnO has been shown in Figure 2b. As can be observed, in both the cases (MoS 2 , MoS 2 @ZnO), three intense peaks at 2 θ ≈14.3°, 39°,, and 49.9° arise corresponding to (002), (103), and (105) planes of MoS 2 .…”

In order to efficaciously harvest these mechanical/bio-mechanical energies, piezoelectric and triboelectric nanogenerators (PENGs and TENGs) are frequently utilized owing to their admirable energy harvesting behaviour. Aside from PENGs, TENGs show a great potential in various applications like pressure, motion, and tactile sensors. [1][2][3][4] The principle of TENGs is based on electrostatic induction and contact electrification where by using frictional force electric charges are generated. The advantage of using TENGs is for its high output power density, high durability, wide choice of materials, and simple design. The contactseparation mode, lateral-sliding and freestanding mode are very well known techniques for enhancement of the TENG output performance. [5][6][7] Among these, contactseparation mode is more efficient for its easy fabrication and good output performance. [8,9] On the other hand in case of PENG the stacked layers don't come in contact with each other and thus, there is no friction between these layers, because the piezoelectric material or composite is stacked between two electrodes. Therefore PENGs are appropriate for powering biomedical devices, [10] micro/nano systems, [11] and wearable electronic devices. [12,13] Thus, from small-scale to large-scale applications, it is very useful to fabricate a device that shows multifunctional mechanism, i.e., piezoelectric as well as triboelectric mechanism for better result. [14] The fabrication of PENGs can be done with different kinds of materials like lead zirconate titanate (PZT), [15] ZnO, [16] BaTiO 3 , [17] and GaN [18] for their good piezoelectric properties. For the enchanting features and different types of potential applications, the twodimensional (2D) layered transition metal dichalcogenides (TMDs) attract a huge attention nowadays. [19,20] Molybdenum disulfide (MoS 2 ) is one such kind of TMDs that has superior, distinctive functional properties that includes high current-carrying capacity and large carrier mobility that come out with emerging applications. [21] MoS 2 has very interesting structure, with different crystal phases such as 1-layer hexagonal unit cell (1H), 2-layer hexagonal crystal cell (2H), and three-layer rhombohedral unit cell (3R). The monolayer MoS 2 (1H) has a fascinating property that can demonstrate piezoelectricity with piezoelectric coefficient (2.99 p.m. V À1 ) to in-plane d11. [22] With increasing the number of odd layer of MoS 2 , its piezoelectricity gradually decreases. [23] The noncentrosymmetric materials are very crucial for creating the mechanical stress that causes the dipole

“…At present, the catalysts that have been reported are TiO2 [3], WO3 [4][5][6], Cu2O [7] and so on. Among them, WO3 material is widely used because of its sufficient reserves in nature, low price, low forbidden bandwidth (about 2.7 eV) [8], can be excited in the visible light range, optical activity, and good stability.…”

Traditional water treatment avoids waste of resources and secondary pollution, photocatalysis technology has become a research hotspot. This paper uses the hydrothermal method to prepare WO3 particles. The microstructure and performance of WO3 were characterized by XRD, SEM, ultraviolet visible light and photocurrent. The results show that the prepared WO3 is a hexagonal crystal with a particle size of about 200-300 nm, and has good absorption properties in the visible light region. Finally, norfloxacin was used as the target pollutant to evaluate its photocatalytic performance. The results show that the prepared WO3 can effectively remove antibiotics in sewage.
