Adsorption toward Cu(II) and inhibitory effect on bacterial growth occurring on molybdenum disulfide-montmorillonite hydrogel surface

Spherical montmorillonite-supported molybdenum disulfide nanosheets as a self-sedimentary catalyst for organic pollutants removal

“…Montmorillonite (Mt) is a natural nanomaterial, has strong adsorption capacity and has been used as a good substrate for supporting MoS 2 [23][24][25][26][27][28][29]. For example, Peng et al designed and successfully fabricated Mt/MoS 2 catalyst with MoS 2 nanosheets intercalating in the interlayer of Mt [30] and MoS 2 nanosheets depositing on the surface of Mt [31].…”

A Multifunctional Microspheric Soil Conditioner Based on Chitosan-Grafted Poly(acrylamide-co-acrylic acid)/Biochar

“…Similarly, the C–O, CO, and O–H peaks were also shifted to a higher binding energy (Figure D,E). More importantly, the high-resolution XPS spectra of the Cu 2p feature (Figure H) could vest in Cu–N and Cu–O, and the binding energies were 933.4 and 932.5 eV, respectively . In summary, from the N 1s and O 1s spectra, we can conclude that there is a coordination effect and electrostatic interaction between Cu 2+ and microspheres, and both oxygen and nitrogen atoms were crucial binding sites for Cu 2+ adsorption in the −COOH, −OH, and −NH 2 groups.…”

Copper phthalocyanine modified hydrogel inverse opal beads for enhanced photocatalytic removal of dyes

“…52 Therefore, the O 1s peak of CuPc-PACA HIOBs is shied towards the direction of high binding energy compared with PACA HIOBs and the Cu 2p peak of CuPc is shied towards the direction of high binding energy compared with CuPc, revealing the coordination of carboxyl and Cu 2+ . 53 The above results indicated the successful modication of CuPc on the PACA HIOBs due to the formation of Cu-O bonds. 54 In addition, UV-vis DRS spectra, PL spectra, photocurrent response, and EIS plots were recorded to evaluate the optical and electrochemical properties of all samples.…”
