To overcome this limitation, a Z-scheme MOF-on-MOF heterojunction was constructed by integrating narrow-bandgap PCN-224 (1.70 eV) with MIL-125 using polyvinylpyrrolidone as a surfactant mediator. The formation of the heterojunction successfully reduced the optical bandgap to 2.23 eV, quantitatively confirming the extended visible-light harvesting. The resulting MIL-125@PCN-224 composite displayed outstanding photocatalytic activity toward methylene blue (MB) degradation. Under visible-light irradiation, it achieved 91.17 % MB (30 mg/L) removal within one hour, with a kinetic rate constant k_app of 0.0233 min⁻¹, which is 3.99 times higher than that of MIL-125. This enhanced performance is ascribed to the direct Z-scheme charge-transfer pathway. Band structure analysis provides quantitative support: the conduction band potentials of MIL-125 and PCN-224 were determined to be −0.63 V and −0.74 V vs. NHE, respectively. This configuration facilitates efficient charge separation while maintaining strong redox power, allowing electrons in PCN-224 to reduce O₂ to generate superoxide anions (·O₂⁻), consistent with the radical trapping and ESR identification of superoxide anions (·O₂⁻) and singlet oxygen (¹O₂) as the dominant reactive species. Furthermore, composite exhibited excellent stability over a wide pH range and maintained high efficiency in real water matrices. These results demonstrate that heterojunction construction is an effective strategy for enhancing photocatalytic efficiency.</div></div>","PeriodicalId":264,"journal":{"name":"Catalysis Today","volume":"467 ","pages":"Article 115694"},"PeriodicalIF":5.3,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146025146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cyclic voltammetry shows that both carbons exhibit measurable ORR activity in 1 M KOH, whereas no significant OER activity was observed. The ORR proceeds mainly through a two-electron pathway producing peroxide intermediates for carbons obtained at 550 °C, while partial graphitization at 1000 °C promotes a mixed two–four-electron process associated with enhanced conductivity and reorganization of edge defects. Straw-derived carbons obtained at 1000 °C displayed higher cathodic currents but also greater instability at anodic potentials, indicating enhanced surface reactivity yet lower corrosion resistance. Overall, sugarcane-derived lignins are shown to be versatile carbon materials.

In this study, glycine was used as a modifier to functionalize 13X zeolite by grafting polar groups, and applied for the removal of oxygenates from Fischer-Tropsch oil. The results indicate that the modified zeolite exhibits a high adsorption capacity for oxygenates. Specifically, the adsorption capacity for butanol, hexanal, and 2-hexanone increased by approximately 90 %, reaching 0.60 g·g⁻¹, 0.36 g·g⁻¹, and 0.35 g·g⁻¹. The adsorption capacity for hexanol and octanol increased by approximately 50 %. The enhancement in adsorption capacity for carbonyl compounds and long-chain alcohols (such as hexanol, heptanol, and octanol) was particularly notable, with an average increase of about 80 %. Mechanistic studies revealed that the adsorption of oxygenates on the modified zeolite is primarily physical adsorption, involving hydrogen bonding interactions and van der Waals forces. The adsorption process can be divided into two stages: surface adsorption and pore diffusion, and is jointly influenced by factors such as zeolite pore size, adsorbate molecular size, and their interactions with the pore channels.

We used <em>Dendrocalamus asper</em> leaf extract (EDA) as a natural precursor, confirming its rich content of secondary metabolites like alkaloids, flavonoids, tannins, saponins, and polyphenols. These compounds play vital roles: alkaloids act as a weak base for synthesis, while others serve as capping agents, ensuring stable nanoparticle formation. Characterization confirmed successful synthesis. Fourier-Transform Infrared Spectroscopy (FT-IR) spectroscopy showed a distinctive Er-O bond vibration at 565.43 cm⁻¹. X-ray diffraction (XRD) analysis revealed a cubic crystalline structure, and UV-Vis Diffuse Reflectance Spectroscopy (DRS) indicated a broad bandgap of 5.2 eV. Scanning electron microscopy (SEM) images displayed spherical, aggregated NPs, and further confirmed their nanoscale size, averaging 21.83 nm. These results collectively affirm the excellent structural, optical, and morphological properties of the synthesized Er₂O₃ NPs. The photocatalytic performance was outstanding. Using malachite green as a model pollutant, the Er₂O₃ NPs achieved a 93.03 % degradation within 120 min under UV light. This degradation followed pseudo-first-order kinetics, with a rate constant (<em>k</em>_obs​) of 1.98 × 10⁻² min⁻¹. The optimized conditions, determined at an initial pH of 6.6, achieved a remarkable 93.03 % degradation. Scavenger experiments were performed to elucidate the mechanism, confirming that the superoxide radical (⋅O₂⁻) is the dominant reactive species responsible for the degradation. Furthermore, the photocatalyst exhibited excellent operational stability, maintaining 85.15 % degradation efficiency even after four consecutive reuse cycles.
