However, the low concentration of CO₂ in the atmosphere necessitates a catalyst with excellent CO₂ enrichment capability. Herein, we designed and synthesized a series of NiO nanosheets featuring oxygen vacancies. Under the condition of pure CO₂ and photosensitizer [Ru(bpy)₃]Cl₂, the yield of CO reaches 16.8 μmol/h with a selectivity of 96%. Through characterization and theoretical calculations, we demonstrate that the presence of oxygen vacancies not only enhances the adsorption capacity of catalysts but also induces lattice distortion in NiO, leading to an increased dipole moment and formation of an internal electric field that facilitates photogenerated carrier separation. Furthermore, we conducted CO₂ reduction reactions under atmospheric condition and surprisingly observed a changing of selectivity from CO to CO and CH₄. A series of control experiments showed that [Ru(bpy)₃]Cl₂ acts as a reduction reaction site due to the presence of O₂ in the atmosphere. Simultaneously, oxygen promotes water splitting, which results in abundant proton generation and subsequent changes in carbon products.</div></div>","PeriodicalId":9832,"journal":{"name":"Chinese Journal of Catalysis","volume":"73 ","pages":"Pages 242-251"},"PeriodicalIF":15.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144572848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the relationship between asymmetric coordination and the spin states of metal sites remains unclear.

Herein, a novel strategy is reported for the rational design of highly loaded Co ASACs (CoN₁C₂/C₂N) immobilized on three-dimensional flower-like C₂N using an in situ-generated carbon defect method. In particular, the asymmetrically tricoordinated CoN₁C₂/C₂N exhibited excellent catalytic activity for sulfachloropyridazine degradation, with a turnover frequency of 36.8 min^–1. Experimental results and theoretical calculations revealed that the electron spin state of the Co-active sites was transferred from the low-spin configuration (<em>t</em>_2g⁶<em>e</em>_g¹) to the high-spin configuration (<em>t</em>_2g⁵<em>e</em>_g²) owing to asymmetric coordination. The high-spin Co 3<em>d</em> orbital in CoN₁C₂/C₂N possessed more unpaired electrons and therefore, had a strong ability to gain electrons from the O 2<em>p</em> orbitals of HSO₅^–, boosting <em>d-p</em> orbital hybridization. More importantly, the spin-electron filling in the σ* orbital of high-spin Co 3<em>d</em>−O 2<em>p</em> accelerated the desorption of *SO₅^•−, which acted as a rate-limiting step in the reaction, thus facilitating more ¹O₂ generation.

Here, we report a redox-mediated strategy to address this bottleneck by designing a hydroquinone-embedded covalent organic framework (Tz-QH-COF) that enables reversible hole buffering and kinetic balance. The hydroquinone (QH) units act as dynamic hole reservoirs, capturing excess holes during ORR and converting to benzoquinone (Q), which is regenerated to QH via WOR, thereby preventing oxidative decomposition. This reversible QH/Q cycle, directly visualized through <em>in situ</em> attenuated total reflection surface-enhanced infrared absorption spectroscopy, ensures unmatched stability, achieving continuous H₂O₂ production for 528 h (22 d) with an accumulated yield of 18.6 mmol L^–1—the highest reported duration for organic photocatalysts. Density functional theory calculations reveal that the QH units exhibit a strong oxygen adsorption energy and favorable two-electron ORR/WOR pathways with low energy barriers.
