Selective oxidation of 5-hydroxymethylfurfural (HMF) to 5-hydroxymethyl-2-furancarboxylic acid (HMFCA) is a promising yet challenging task, producing significant chemical feedstocks. The development nonprecious and efficient catalytic system for biomass-derived HMF great importance HMFCA production. Herein, magnetic Ag/GO/Fe3O4/γ-Fe2O3 nanocomposite with p–n heterojunctions was fabricated using simple refluxing method followed by an autoclave step at 120 °C. employed as photocatalyst the selective toward high conversion (99%) selectivity (98%). products were separated determined high-performance liquid chromatography-ultraviolet. structural integrity synthesized corroborated Fourier-transform infrared, field emission scanning electron microscopy, energy dispersive X-ray, transmission vibrating sample magnetometer, dynamic light scattering, X-ray diffraction, photoelectron spectroscopy, diffuse reflectance photoluminescence, BET-BJH. Various parameters checked, such temperature, amount catalyst, time, base, sources, intensity, recyclability, efficiency photocatalyst. In result, highest photocatalytic (98%) obtained 0.03 mol % under green emitting diode irradiation (12 W) 1.5 h. Therefore, protocol provides route enhance properties performance semiconductor materials synthesizing value-added chemicals environmentally friendly conditions.

Zinc Chloride-Doped g-C₃N₄ Microtubes for Enhanced Photocatalytic Degradation of Tetracycline Hydrochloride

Langmuir, Год журнала: 2025, Номер unknown

Опубликована: Янв. 14, 2025

Morphology regulation and element doping are effective means to improving the photocatalytic performance of graphite-phase carbon nitride (g-C3N4). In this article, using melamine zinc chloride as raw materials, a novel kind Zn/Cl-doped hollow microtubular g-C3N4 (Zn-HT-CN) by hydrothermal method was developed. The structure morphology Zn-HT-CN reference samples were characterized X-ray diffraction patterns (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), photoelectron (XPS), etc. Zn/Cl narrowed bandgap width g-C3N4, well inhibiting recombination photogenerated holes. Compared with pure microtube, showed excellent catalytic for photodegradation tetracycline hydrochloride (TCH) under irradiation visible light. rate TCH reached 94.41% in 40 min, which about two times high that catalyzed microtube. Moreover, it also superior microtube doped other typical metal elements. addition, good tolerance environmental pH, efficiency material remained at 78.78% after five cycles.

Tetracycline (TC), a widely prescribed antibiotic to treat bacterial infections in humans and animals, poses substantial threat the environment due its extensive use. To address this issue, TiO2-based photocatalyst was employed for effective sonophotocatalytic degradation of TC. The ultrasound-driven TiO2 synthesis induced oxygen vacancies Ti3+ species, enhancing efficiency. formation confirmed by using various analytical techniques. synthesized with ultrasound (TiO2 US) demonstrates remarkable TC under halogen lamp irradiation, achieving an efficiency ∼96%, 1.56 times higher than that without WUS). Under diffuse sunlight, US WUS exhibit efficiencies 95 79%, respectively. Notably, effectively degraded hospital effluent, 83% This nanophotocatalyst displays appreciable reusability stability, offering promising solution efficiently degrading persistent emerging contaminants.
