In this paper, the Linze Pal was used as the support to prepare a series of Mn-Ce/Pal catalysts for catalytic oxidation of toluene. The catalysts were characterized by XRD, BET, Raman, XPS spectroscopy and TEM analysis. The results indicated that the particle sizes of Mn oxides were decreased and the dispersions were improved after doping with cerium. The strong interaction between Mn and Ce oxides increased the specific surface area, the content of Mn³⁺ and Ce³⁺ and the surface-adsorbed oxygen species of the Mn-Ce/Pal catalysts with the decrease of doping amount of cerium, which had significant effect on the catalytic activities of the catalysts for toluene oxidation. The 5 %Mn_0.9Ce_0.1/Pal catalyst exhibited the best performance for toluene oxidation and had a T₉₀ at 318 °C; meanwhile, this studied catalyst also displayed high long-term and regeneration stabilities.

It is worth highlighting that CZC-LDH facilitates Cl adsorption for the ClOR (Chloride Oxidation Reaction) leading to the production of active chlorine contributing to indirect oxidation of MB. An increase in the production rate of active chlorine improved the oxidation process by increasing the applied potential.

It was revealed that the Si-OH groups of MDPal interacted with the metal ions during the extrusion process and contributed to the shaping formation of the precursor. The MDPal provided component doping for adjusting the color properties of nanocomposite pigments and the mixed-dimensional morphology served as benign substrate for supporting CoAl₂O₄ nanoparticles without obvious aggregations.

Palygorskite (Pal) was coated with a molecular sieve (type: MCM–41) via an in–situ growth method, and the resulting composite (Pal/M) was further modified with 3–aminopropyl triethoxysilane (APTES) to prepare NH₂–Pal/M through post–synthesis modification.

The thickening property of organophilic montmorillonite is influenced by montmorillonite composition and nature of the organic compounds. In order to improve the thickening ability of organophilic montmorillonite to obtain a stable and excellent lubricating performance of montmorillonite grease, synthetic montmorillonite with the uniform composition is an effective solution. Organophilic montmorillonite as a thickener usually uses a single long-chain quaternary ammonium salt to modify montmorillonite, which limits to further improve thickening ability. To address these issues, a new modification strategy was applied by selecting a very short chain quaternary ammonium salts and a long chain quaternary ammonium salts to co-modify synthetic montmorillonite. Synthetic organophilic montmorillonite was obtained through the co-intercalation of tetramethylammonium chloride (TMAC) and octadecyl trimethyl ammonium chloride (OTAC). Due to the huge difference in alkyl chains between TMAC and OTAC, the specific surface area and the number of mesopores of organophilic montmorillonite increased significantly. Molecular dynamics simulation further proved that TMAC entered the interlayer space and caused changes in the arrangement of interlayer organics. The interlayer space, organic content, and specific surface area can be effectively controlled by adjusting the molar ratio of TMAC and OTAC. The results revealed that molar ratio of TMAC and OTAC 2:8 was optimal, and the thickening ability of organophilic montmorillonite was equivalent to 5 times that of only OTAC. Tribological tests showed the grease exhibited good anti-wear ability and stable friction reduction at 180 °C. Due to the convenience of the synthetic method used and its superior rheological and tribological performance, this study may provide new insights into colloid, interface chemistry, and materials science to prepare organophilic montmorillonite.</div></div>","PeriodicalId":245,"journal":{"name":"Applied Clay Science","volume":"265 ","pages":"Article 107671"},"PeriodicalIF":5.3,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143155223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, four distinct ratios of nanohybrids were obtained by introducing palygorskite clay into selenium disulfide particles.

The results show that as the palygorskite content in the hybrid increases, its colloidal stability initially exhibits a significant enhancement, followed by a subsequent weakening, reaching the optimal ratio of selenium disulfide to palygorskite at 1:3 (hybrid-25). The results of particle size, zeta potential, and contact angle indicate that colloid stability is mainly determined by the thickness of the particle hydration shell and the intensity of Brownian motion, and is basically independent of the surface charge. The SEM, TEM, XRD, FTIR, and XPS results reveal the formation mechanism of the hybrid, which first forms a package of palygorskite nanorod crystals on the surface (shallow) area of selenium disulfide particles through grinding, and then achieves complete and uniform hybridization of the two through a melting-impregnation method, which results in a leap from micrometer to nanometer.
