However, it was unclear what the roles of atoms in H₂O in subsequent oxidation of these products. In this study, the photocatalytic oxidation of two aromatic alcohols, benzyl alcohol and phenethyl alcohol, on TiO₂ (79 % anatase and 21 % rutile) were investigated in mixed H₂O (or H₂¹⁸O, D₂O) and O₂ system. Aromatic aldehydes, acids and esters were main aromatic products, while modified TiO₂ and isotope-containing H₂O did not change the product species. Aromatic aldehydes showed ≤ 0.19 % and ≤ 1.58 % of ¹⁸O- and D-labeling rates, suggesting hardly involvement of H₂O in their formation. Aromatic acids exhibited a ¹⁸O-labeling rate range of 28.12 %-40.33 % and the highest D-labeling rate of 0.76 %, while a maximum enhancement of ¹⁸O-labeling rate was 0.11 % in the –C=O group of the acids, indicating that H₂O selectively provided O atom in the formation of –OH group of aromatic acids. The ¹⁸O- and D-labeling rates of aromatic esters were in the range of 9.01 % to 15.95 % and 1.73 % to 8.08 %, suggesting that both oxygen and hydrogen atoms from H₂O contributed to aromatic ester formation. Further analyzing mass fragmentation confirmed that H₂O separately contributed its hydrogen and oxygen atoms to the –C=O and R–O groups of the esters. Based on the isotope tracing results, the contribution roles of H₂O’s hydrogen and oxygen atoms in oxidation of aromatic alcohols to corresponding aromatic products were proposed. The findings in this study help to clarify the role of H₂O in the oxidation process of aromatic alcohols at the atomic level and comprehensively reveal the oxidation mechanism of the aromatics.</div></div>","PeriodicalId":16782,"journal":{"name":"Journal of Photochemistry and Photobiology A-chemistry","volume":"467 ","pages":"Article 116447"},"PeriodicalIF":4.1,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143874569","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}

RDT is based on chemicals that produce reactive oxygen species (ROS) under X-ray irradiation. Recently, several radiosensitizers are being developed and characterized as producers of ROS under UV irradiation. Therefore, in this study, we focused on MAAs as radiosensitizers, and evaluated ROS production from MAAs and aromatic amino acids under X-ray and UV irradiation. Aromatic amino acids were selected because they have structures similar to those of MAAs. MAAs showed radical scavenging abilities but did not produce ROS under X-ray and UV irradiation. The fact that MAAs did not function as ROS producers under X-ray irradiation indicates that they are not suitable for RDT applications; however, because they did not produce ROS under UV irradiation, they might be important for application in the production of cosmetics. Surprisingly, histidine produced hydroxyl radicals and superoxide anions under UV and X-ray irradiations.

Thus, TiO₂-based photocatalysts are prepared at room temperature via aqueous sol–gel synthesis. These photocatalysts are doped with different molar ratios of dopants. The physicochemical properties of the obtained photocatalysts are characterized using various complementary techniques. X-ray diffraction (XRD) is used to determine the distribution of different crystalline phases of TiO₂ and the proportion of amorphous TiO₂ in the samples. BET measurements give textural properties with specific surface area reaching up to 292 m²/g and TEM images illustrating their spherical morphology. Inductively coupled plasma atomic emission spectroscopy (ICP-AES), energy-dispersive X-ray spectroscopy (EDX), and X-ray photoelectron spectroscopy (XPS) analyses confirmed the presence of Ti, O and Ta, V or Nb elements in the samples. Additionally, XPS spectra highlights the incorporation of nitrogen in the undoped synthesized TiO₂. Additionally, band gap widths measured by UV–vis diffuse reflectance spectroscopy (DRUS) are done to see the impact of the dopants on the bandgap, with V-doping reducing its value from 2.95 to 1.88 eV. A screening of the photocatalytic activity of undoped and doped photocatalysts is carried out by evaluating the degradation of p-nitrophenol under UV–visible light (300 &lt; λ &lt; 800 nm) and visible light only (395 &lt; λ &lt; 800 nm).

Photocatalytic tests show an improvement in the activity of the photocatalyst when doped with tantalum and niobium (from 22 % with undoped TiO₂ under visible light to 37 % and 55 % with the best Ta and Nb-doped samples respectively), while a notable decrease in activity is observed with vanadium doping (dropping to 3–12 % with the V-doped series). Finally, a preliminary electrophotocatalysis experimental setup is implemented and appears to show an improvement in the mineralization of the PNP solution when the anode is coated with layers of the best doped-TiO₂ material (Nd doping), compared to an uncoated anode (the mineralization rate increases from 72 % to 94 %).</div></div>","PeriodicalId":16782,"journal":{"name":"Journal of Photochemistry and Photobiology A-chemistry","volume":"467 ","pages":"Article 116453"},"PeriodicalIF":4.1,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877047","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}

Graphitic carbon nitride (g-C₃N₄) has garnered considerable attention and emerges as a promising candidate for photocatalytic CO₂ reduction, owing to its visible light absorption, metal-free, and environmentally benign nature. However, its ability to effectively achieve this is currently hindered by several factors such as relatively low surface area, fast electron-hole recombination rate and limited CO₂ adsorption capacity, which also constrain its practical applicability. In this work, a novel photocatalyst was synthesized by incorporating a suitable amount of ZIF-8 derived N-doped porous carbon into g-C₃N₄ without affecting its light absorption capacity. The as-prepared samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), nitrogen and CO₂ adsorption measurements, X-ray photoelectron spectroscopy (XPS), UV–Vis diffuse reflectance absorption spectra (UV-DRS), and photoluminescence spectroscopy (PL). Compared to g-C₃N₄, the optimized photocatalyst exhibited a 54-fold increase in surface area, a 3.5-fold enhancement in CO₂ adsorption capacity, a reduced optical bandgap, and significantly superior photocatalytic activity for CO₂ reduction, achieving CH₄ production at 70.87 μmol h⁻¹ g⁻¹ and C₂H₆ production at 35.31 μmol h⁻¹ g⁻¹.
