... The degradation of ciprofloxacin was significantly enhanced by the photocatalytic activity of Bi/BiOF/Bi/BiOF/ Bi 2 O 2 CO 3 , which was 7 and 3.5 times greater than that of BiOF and Bi/BiOF/Bi 2 O 2 CO 3 respectively. [270] The Y-doped bismuth oxy fluoride/reduced graphene oxide (Y-BiOF/RGO) composite was synthesized using a straightforward solvothermal technique. The synthesized composite has been studied employing techniques that include transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), photoluminescence spectroscopy (PL), UV-Vis diffuse reflectance spectroscopy (DRS), FT-IR, and X-ray diffraction (XRD). ...

... Generally, the total friction between layers and surfaces of layered 2D materials is composed of internal friction and edge friction. In 2D materials with small sizes, the friction is mainly caused by the edges [49,84,95,110]. Especially for heterogeneous structures, the contribution of edge atoms to friction is one to two orders of magnitude larger than that of in-plane atoms [111]. ...

... Supported metal catalysts are important catalysts for catalytic hydrogenation and upgrading of oil products in reducing the content of aromatics. Metal sulfides (CoMoS, NiMoS) [3][4][5] and metals (Ni, Pt, Pd) [6][7][8][9][10] were widely studied in this kind of reaction as active components. Metal sulfide catalysts can effectively improve the resistance of catalysts to sulfur, but the reaction conditions were harsh. ...

... Therefore, the potential of green mussel shells as a material for HA synthesis will be examined in this research. 14 Green mussel shells contain two polymorphs of calcium carbonate (CaCO 3 ), namely calcite and aragonite. 15 Most organic compounds can be found among the crystallites (intercrystalline), but some organic molecules (intercrystalline) are also intercalated in the crystal lattice. ...

... However, dye wastewater contains a large amount of azoles and polycyclic aromatics that are challenging to degrade [2], which leads to environment pollution and serious threat to human health [3,4]. To solve those problems, various methods, including adsorption [5][6][7], flocculation [8][9][10][11], biological oxidation [12][13][14], and photodegradation [15][16][17][18] are employed. Among these, photodegradation technology has garnered significant attention due to its merits, such as high efficiency, low cost, and ease of operation [19]. ...

... Additionally, the photo-corrosion phenomenon can be developed due to the low migration efficiency of photo-excited charge carriers, further limiting the photocatalytic activity of Bi 5 O 7 I [90]. Fortunately, a series of adequate optimizing modifications, like semiconductor composites, noble metal doping, and surface engineering, can be harvested to strengthen solar light utilization and improve the optical properties of Bi 5 O 7 I-based heterojunction [91]. ...

... In Fig. 7a, the 0.2CBO/BMO curve exhibited the smallest radius, confirming that the electron transfer efficiency of 0.2CBO/BMO was greater than that of CBO and BMO. Additionally, the current density of 0.2CBO/BMO was much greater than that of CBO and BMO, providing evidence that the combination of CBO and BMO effectively promoted the migration of photogenerated carriers (Fig. 7b) [44][45][46]. Figure 8a shows the degradation curve of TC using a series of photocatalysts under visible light conditions. Prior to photocatalytic degradation, the reaction system was placed in a dark environment and stirred for 30 min to achieve adsorption equilibrium. ...

... After composited into the MoS 2 -Zn coatings, it remained the same antibacterial mechanism as MoS 2 particles, described as follows: Under light irradiation, MoS 2 in the MoS 2 -Zn coatings were excited, leading to the transition of e − from the valence band (VB) to the conduction band (CB), and then leaving h + on the VB. The sufficiently reducing e − on the CB of MoS 2 trapped dissolved oxygen in the water and reacted by catalytic reaction to produce the dominant active radicals ⋅O 2 - [70]. Meanwhile, H 2 O was also catalyzed by a small amount of ⋅O 2 to produce ⋅OH [71], which was tested as the subordinate active radical in the antifouling process. ...

... Liu et al. [20] prepared an in situ Z-scheme Bi 2 MoO 6 /AgI heterojunction, where the photogenerated electrons at the heterojunction interface were effectively transferred from AgI to Bi 2 MoO 6 , which exhibited excellent photocatalytic activity for the degradation of malachite green (MG). Compared with conventional heterojunction structures, p-n heterojunctions are more favorable for carrier separation due to their unique energy band structure and carrier transport properties [21,22], such as Bi 2 MoO 6 /KNbO 3 [23], BiOBr/Bi 2 MoO 6 [24], and Bi 2 MoO 6 /CuBi 2 O 4 [25]. Particularly, CuS as a conventional p-type narrow band gap semiconductor has recently attracted attention due to its excellent photoelectrochemical properties, low toxicity, and structural stability [26,27]. ...
