Fabrication of novel magnetic CuS/Fe3O4/GO nanocomposite for organic pollutant degradation under visible light irradiation

A sustainable approach for the adsorption of methylene blue from an aqueous background: an adsorbent based on DES/CGS modified GO@ZrO2

“…100 The increase in the P value with pH finds support in an earlier study in which MB adsorption has been conducted on a GO-based composite. 26 However, the amount of MB adsorbed from pH 4–8 for CGS-GO@ZrO 2 is nearly constant. The former form will interact electrostatically with the CGS-GO@ZrO 2 surface while the latter one will interact hydrophobically.…”

“…NCs have been shown to be used as a potential material to solve the above mentioned problem using various modications. 26,[86][87][88][89][90] Owing to the economic and synthetic characteristics of ZrO 2 and DES, respectively, both are chosen for NC synthesis with GO and for further functionalization (DES-GO@ZrO 2 ). Moreover, another similar composite has been synthesised and modied with CGS using a method reported elsewhere.…”

Tetracycline degradation in the Fe3O4@HKUST-1/persulfate system: properties, activation mechanism, and degradation pathways

“…The point of zero charge (pHpzc) is the pH value at which the surface charge of a composite material is neutral. 31,32 When the pH falls below pHpzc, the material surface is positively charged. 33 Conversely, when the pH exceeds pHpzc, the material surface becomes negatively charged.…”

Deep Eutectic Solvent/Surfactant-Engineered GO@TiO2 Advanced Material for Sustained and Ultrafast Adsorption of Hazardous Dye from Contaminated Aqueous Environment

“…51 The increase in the P value with pH is consistent with a previous study that investigated MB adsorption on a GO-based composite. 12 When the pH exceeds the pK a , MB dye molecules are present in their cationic form. 52 Therefore, raising the pH of the dye solutions led to an increase in the electrostatic attraction between the positively charged MB molecules and the negatively charged NCs surface.…”
