The effective separation of products and the efficient recovery of catalysts and emulsions are key considerations in the design and development of Pickering emulsion systems. Here, we synthesized chitosan-based amphiphilic microgels whose functional groups can bind to metals through coordination. The poly(<em>N</em>-isopropyl acrylamide) (PNIPAM) contains a temperature-sensitive group, which could show hydrophilicity at a low temperature and display hydrophobicity at a high temperature. Meanwhile, its ligands (such as carboxyl groups) can respond to pH changes through protonation and deprotonation: at low pH, protonation increases hydrophilicity and surface charge, while at high pH, deprotonation reduces the charge and increases hydrophobicity, thereby altering the surface activity of the particles and enabling pH-controlled emulsification. In ethyl acetate catalytic application, the reactants (ethanol and acetic acid) are dissolved in the aqueous phase, while the product, ethyl acetate, is dissolved in the organic phase (toluene). Porcine pancreatic lipase (PPL) supported on a microgel catalyzes the esterification reaction, while co-loaded Zn²⁺ stabilizes the enzyme’s conformation. The synergistic action of these two components enables the efficient synthesis of ethyl acetate. Finally, the reactants and products could separate with the separation of water and toluene, and the catalysts could be recycled.

Our results identify the CrTe₃ monolayer as a ferromagnetic semiconductor with an indirect band gap of 0.45 eV, exhibiting a distinctive triaxial magnetic anisotropy. Further analysis demonstrates that this anisotropy originates from the combined contributions of magnetic dipole−dipole interactions (shape anisotropy) and spin−orbit coupling (magnetocrystalline anisotropy).

Herein, nanostructured Fe₂O₃ and metal-modified Fe₂O₃ photocatalysts (M = Ni, Cu, Mo, Ru, and Pt) were investigated for gas-phase photocatalytic nitrogen conversion under visible-light irradiation in N₂/H₂ mixtures. The materials were characterized by BET, X-ray diffraction, X-ray photoelectron spectroscopy, ultraviolet photoelectron spectroscopy, and UV−vis DRS to examine relationships between phase composition, surface chemistry, electronic structure, and photocatalytic response. Although samples retained hematite as the crystalline phase and displayed similar optical band gaps, metal incorporation produced distinct secondary phases, surface chemical environments, and band-edge positions. Among the catalysts, Mo/Fe₂O₃ showed the highest NH₃ formation after prolonged irradiation, whereas Ni/Fe₂O₃ displayed a quasi-steady-state behavior. Pt/Fe₂O₃ exhibited a distinct response, with the detection of N₂H₄ suggesting hydrogenation-favored pathways, consistent with the presence of surface-accessible Pt⁰ species. In contrast, Cu/Fe₂O₃ showed limited NH₃ formation, in agreement with its lower H₂ consumption and less favorable hydrogenation behavior under the applied conditions. Overall, the results indicate that gas-phase photocatalytic nitrogen conversion over nanostructured metal-modified Fe₂O₃ cannot be explained by a single unified band-alignment framework but rather by the combined influence of phase composition, surface oxygen chemistry, electronic structure, and the balance between N₂ and H₂ activation.</p>","PeriodicalId":6,"journal":{"name":"ACS Applied Nano Materials","volume":"9 40","pages":"18764–18782"},"PeriodicalIF":5.8,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149153090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we focused on the hydrothermal synthesis of tin sulfide (SnS_<em>x</em>) embedded on SrTiO₃ to form nanocomposites with varying weight percentages (5%, 10%, 15%, and 20% wt) for photocatalytic hydrogen production.
