Traditional wastewater treatment technologies often demonstrate limited efficiency in removing such contaminants. In this study, we developed a series of titanium-doped Bi₂MoO₆ (Ti-BMO) photocatalysts via a simple solvothermal method for the efficient visible-light-driven degradation of ciprofloxacin (CIP). Characterization revealed that Ti⁴⁺ions selectively substituted Bi sites within the lattice, inducing lattice distortion and oxygen vacancy formation for charge compensation. These oxygen vacancies not only function as electron traps, promoting the efficient separation of photogenerated carriers, but also serve as active sites for interfacial reactions. The optimized 3% Ti-BMO catalyst achieved a 94.6% CIP degradation efficiency within 120 min, approximately 1.38 times that of pristine BMO, with a pseudo-first-order rate constant increased by 2.11-fold. Furthermore, the catalyst demonstrated outstanding stability and reusability over five consecutive cycles.

We recently reported a repurposed cytochrome P450_BM3 that catalyzes enantioselective MHAT cyclization reactions using hydrosilanes as hydride sources. A practical limitation of this enzymatic transformation is the requirement for superstoichiometric amounts of hydrosilane, which limits its practicality and industrial relevance. To overcome this limitation, we applied a Bayesian optimization algorithm based on Gaussian regression to minimize hydrosilane usage while maintaining high yield and enantioselectivity. Using either PhSiH₃ or MePhSiH₂ as hydride source, we simultaneously optimized multiple reaction parameters, including pH, substrate concentration, surfactant loading, and hydrosilane stoichiometry. For reactions employing PhSiH₃, hydrosilane consumption could be reduced from 20 equivalents to 4 equivalents without compromising yield or enantioselectivity. These optimized conditions were broadly applicable across different diene substrates. When MePhSiH₂ was used, the Bayesian optimization identified distinct parameters, affording twofold higher yields than under the reported conditions. Collectively, this study confirms the power of Bayesian optimization for efficiently navigating the parameter hyperspace and provides practical conditions that enhance the applicability of enzymatic MHAT chemistry.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":508,"journal":{"name":"Catalysis Letters","volume":"156 7","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148154243","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}

With NaBH₄ serving as a reducing agent, the resulting Ag nanoparticles exhibited a quasi-spherical morphology with particle sizes ranging from 5 to 50 nm and a face-centered cubic crystal structure. Notably, the N-doped CDs/Ag nanocomposites demonstrated markedly enhanced catalytic activity toward the reduction of 4-nitrophenol (4-NP) compared with the undoped CDs/Ag nanocomposites. Kinetic analysis revealed pseudo-first-order behavior, with the N-doped CDs/Ag nanocomposites exhibiting significantly higher apparent rate constants (k_app of 0.99 vs. 0.31 min^− 1) and specific activity factors (k_norm of 495000 vs. 155000 min^− 1 g^− 1).

In this study, a series of Zn–Ni/ZSM-5 bimetallic catalysts were successfully synthesized via a two-step in-situ hydrothermal method, wherein Zn and Ni species were confined within the ZSM-5 zeolite matrix. Their catalytic performance was systematically evaluated in the liquid-phase hydrogenation refining of trace unsaturated impurities in industrial-grade coal-based ethylene glycol (rather than hydrogenation of the bulk ethylene glycol solvent). The structure and physicochemical properties of the catalysts were comprehensively characterized by XRD, SEM, XPS, H₂-TPR, NH₃-TPD, and HAADF-STEM. The results reveal that Zn and Ni species are uniformly dispersed within the ZSM-5 channels and exhibit a significant electronic synergy, wherein electron transfer from Zn to Ni increases the electron cloud density of Ni species, enhances their reduction stability, and promotes the homogenization of the Ni chemical environment. Under optimal reaction conditions (120 °C, 0.8 MPa H₂, LHSV = 2.26 h⁻¹), the 9%Zn-3%Ni/ZSM-5 catalyst exhibited the best hydrogenation performance, achieving UV transmittances of 64, 97, and 100% at 220 nm, 275 nm, and 350 nm, respectively.
