The bioactive glass ceramic prepared by hydrothermal method doped with different concentration of SrO. The materials have been characterised using X-ray diffraction (XRD), scanning electron microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS), UV-Visible spectroscopy and in vitro bioactivity tested in Hank’s balanced salt solution at 37 °C for 7 days. The formation of hydroxyapatite layer has been confirmed by the XRD, SEM and EDS. SrO-5 sample shows the highest degradation of methylene blue dye which is 97.14% at 700 rpm degraded in 180 min. Superoxide radicals and holes are the main active species that are essential to the tribocatalytic process, according to the findings of the active species quenching experiment. SrO-5 have the potential to be used in biomedical application like bone tissue engineering and dentistry as well as dye wastewater treatment by harnessing ambient friction energy due to their exceptional tribocatalysis activity.

Herein, we investigate the influence of pyrolysis temperature (800–1100 °C) on Co–N/C catalysts derived from ZnCo-ZIF for the aerobic oxidation of 5‑hydroxymethylfurfural (HMF) to 2,5‑furandicarboxylic acid (FDCA). A volcano‑shaped dependence of FDCA yield on pyrolysis temperature is observed, with the catalyst pyrolyzed at 1000 °C (Co–N/C-1000) delivering complete HMF conversion and 98.0% FDCA yield within 4 h under optimized conditions (110 °C, 2 MPa O₂). Multi-technique characterization reveals a temperature-driven evolution of Co species: from atomically dispersed Co–N_x sites at 800–900 °C, to a bimodal configuration comprising abundant Co–N_x together with a small amount of metallic Co⁰ nanoparticles at 1000 °C, and finally to large Co aggregates at 1100 °C. The optimal catalytic performance at 1000 °C is thus attributed to this unique coexistence. Kinetic analysis confirms the consecutive pathway HMF → HMFCA → FFCA → FDCA with FFCA→FDCA as the rate‑determining step. Notably, the optimal catalyst maintains 96.8% FDCA yield under industrially relevant 5 wt% HMF concentration. This work provides insights into the structure-performance relationship of Co–N/C catalysts and a rational strategy for designing efficient non-noble metal catalysts for biomass conversion.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":508,"journal":{"name":"Catalysis Letters","volume":"156 9","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148837933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, pristine Zn-based MOF (MOF-5) generally exhibits poor catalytic activity due to its wide band gap, limited visible-light absorption, and rapid recombination of photogenerated charge carriers. In this work, these limitations were addressed by amine functionalization and Fe₂O₃ nanoparticle incorporation, leading to the construction of a multifunctional Fe₂O₃@NH₂-MOF-5 heterostructured catalyst through a facile synthesis strategy. Structural and optical characterizations supported the successful formation of the composite and revealed enhanced visible-light absorption and a reduced band gap compared with pristine MOF-5. Electrochemical measurements showed that Fe₂O₃@NH₂-MOF-5/NF exhibited improved oxygen evolution reaction (OER) activity, requiring an overpotential of 230 mV at 10 mA cm⁻² with a Tafel slope of 58 mV dec⁻¹, together with enhanced hydrogen evolution reaction (HER) performance, delivering an overpotential of 94 mV at 10 mA cm⁻². Furthermore, the composite achieved 86% Rhodamine B (RhB) degradation within 60 min and a hydrogen evolution rate of 146.81 µmol g⁻¹ h⁻¹ under light irradiation. Based on the band structure analysis and photocatalytic performance, a proposed Z-scheme charge-transfer pathway provides a plausible explanation for the enhanced catalytic activity by facilitating charge separation while preserving strong redox capability. This work demonstrates that amine functionalization combined with Fe₂O₃ incorporation is an effective strategy to overcome the intrinsic limitations of MOF-5, enabling the development of efficient multifunctional catalysts for water splitting and environmental remediation.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":508,"journal":{"name":"Catalysis Letters","volume":"156 9","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148837934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
