Influence of Ag nanoparticles anchored on protonated g-C₃N₄–Bi₂MoO₆ nanocomposites for effective antibiotic and organic pollutant degradation

Abstract

The development of noble metal-anchored semiconductors for photocatalytic processes is now garnering interest for potential application to toxic pollutants as well as antibiotic degradation.

Promoting Spatial Charge Transfer of ZrO2 Nanoparticles: Embedded on Layered MoS2/g-C3N4 Nanocomposites for Visible-Light-Induced Photocatalytic Removal of Tetracycline

“…As shown in Figure a,b, bare ZrO 2 can be coded for tetragonal (JCPDS card 79-1769); its fundamental diffraction patterns at 24.2, 28.2, 31.5, 34.1, 35.3, 40.7, 50.1, and 55.3° can be assigned to (011), (111), (111), (002), (211), (202), (013), and (131) planes, respectively. The firm and spire diffraction peaks of ZrO 2 confirm the high purity and crystallinity of the sample. , The primary peaks of bare g-C 3 N 4 are located at 13.1 and 27.4°, respectively, and correspond to the crystal planes (100) and (002) . It has been observed that there are no distinctive peaks of g-C 3 N 4 and MoS 2 in the ZrO 2 @MoS 2 /g-C 3 N 4 nanocomposite (Figure a,b) even though these peaks can be seen in the transmission electron microscopy (TEM) pictures.…”

Dual catalytic activity of hexagonal Mg–Sr codoped ZnO nanocrystals for the degradation of an industrial levafix olive reactive dye under sunlight and biosensing applications

“…The catalyst's crystalline structure and morphological characteristics are not lost after numerous cycles, as shown by XRD patterns and SEM images of both fresh and used nanocrystals. 39 The 0.06 M Mg-Sr codoped ZnO photocatalyst was shown to be stable after repeated use since all of the diffraction peaks of the reused 0.06 M Mg-Sr codoped ZnO photocatalyst were in good agreement with those of the fresh 0.06 M Mg-Sr codoped ZnO photocatalyst (Fig. 1).…”

Mechanistic insight into the photocatalytic degradation of organic pollutants and electrochemical behavior of modified MWCNTs/Cu–Co3O4 nanocomposites

“…The XRD patterns and SEM images of the fresh and recycled samples show that the crystallinity and morphological characteristics of the catalyst are unchanged even after five runs. 76 Table 3 compares the highest degradation capacities of EY to published values of degradation % for other catalysts. Cu–Co 3 O 4 had greater maximal degradation capacities for EY at 300 min than other materials, which might be attributed to its larger specific surface area and band gap alignment.…”
