Summary: Three-dimensional mesoporous lepidocrocite-type layered sodium titanate (LST) was constructed through electrostatic interaction at room temperature, exhibiting superior adsorption properties for cationic dyes. An ion-exchange mechanism was proposed for cationic dye adsorption on LST, suggesting stoichiometric exchange between Na+ ions in the LST interlayer and dye molecules in solution.

Summary: Photocatalytic hydrogen production using graphitic carbon nitride (g-C3N4) is a promising strategy for utilizing solar energy. This study synthesized an intramolecular donor-acceptor (D-A) structured g-C3N4 nanosheet photocatalyst, which exhibited enhanced charge carrier separation and improved photocatalytic activity. By integrating the intramolecular D-A system and ultra-thin nanosheet structure, this photocatalyst showed extended absorption edge and increased specific surface area. This work offers valuable insights for developing D-A-modified photocatalytic materials for solar energy conversion.

Summary: The insertion of phosphotungstic acid (PTA) and zirconia (ZrO2) into mesoporous MCM-41 significantly improved the acidic strength and surface acidity of the composite material. After determining the optimal catalytic activity and surface acidity of 25.0 wt% PTA/Zr-MCM-41, adsorption experiments revealed that this composite has high adsorption capacity for Methylene Blue (MB).

Summary: In this study, two acrylate-modified hydrochars were synthesized by grafting acrylic acid onto the surface of hydrochars. The hydrochars used were carbonized in water and acidic medium, respectively. It was found that one of the hydrochars was more prone to free radical polymerization and had a higher carboxylate content after modification. The modified hydrochar showed higher adsorption capacity for methylene blue and lead ions. The adsorption mechanism involved complexation, ion exchange, electrostatic interaction, H-bonding, and p-p interaction. This study suggests that one-step modification method has great potential for preparing carboxylate-modified hydrochars for cationic pollutant adsorption.

Summary: The ultra-high adsorption capacity and mechanical property of a poly(acrylic acid)/laponite nanocomposite hydrogel have been achieved by combining physical cross-linking with sparse chemical cross-linking. The hydrogel demonstrates porous 3D network structures and high water penetration, resulting in fully exposed adsorption sites and facilitating adsorption. With an adsorption capacity of 3846 mg/g for methylene blue, this hydrogel shows promising potential as an efficient super adsorbent for water treatment.
