This study systematically investigates the effect of methanol–water mixtures on zeolitic imidazolate framework-8 (ZIF-8) synthesis to elucidate solvent-mediated nucleation and growth behavior. ZIF-8 was synthesized using mixed solvent with methanol volume ratio ranging from 0 % to 100 % and characterized by several techniques including transmission electron microscopy (TEM), X-ray diffraction (XRD), nitrogen (N₂) and carbon dioxide (CO₂) adsorption, and thermogravimetric analysis (TGA). These results suggest complex correlations between solvent composition and particle morphology, crystallinity, porosity, and yield. Particle size decreases from ∼123 nm in water to ∼50 nm in methanol, accompanied by a transition from rounded to faceted rhombic dodecahedra. XRD analysis shows that crystallite size decreases with increasing methanol content, whereas a 50:50 methanol-water mixture produces the highest Brunauer–Emmett–Teller (BET) surface area (∼1465 m²/g) and a balanced micro-to mesoporosity. Yield calculation suggests a trade-off between productivity and structural characteristics: water-rich mixtures achieve higher yields (∼92 %), while methanol-rich conditions yield smaller, more defective crystallites but promote enhanced textural porosity. These findings suggest that co-solvent system provides a tunable physicochemical environment that governs nucleation kinetics and particle growth, establishing a rational framework for optimizing scalable, high-quality ZIF-8 production.</div></div>","PeriodicalId":378,"journal":{"name":"Journal of Solid State Chemistry","volume":"355 ","pages":"Article 125787"},"PeriodicalIF":3.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145787517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a novel Tb@Zr-MOF with dual emission signals (I₃₉₁, I₄₂₆ from Zr-MOF, I₄₉₀, I₅₄₆, I₅₈₆, I₆₂₂ from Tb³⁺) was fabricated by anchoring Tb³⁺ ions into a Zr-MOF inherently possesses bright blue fluorescence, utilizing the principles of antenna effect and photo-induced electron transfer (PET).
