Neutral red, a cationic dye commonly found in wastewater, obstructs photosynthesis in aquatic ecosystems and carries potential toxicity. Traditional methods of dye removal often prove ineffective due to the chemical stability of these compounds. In this study, oxygen-doped graphitic carbon nitride (O-doped g-C<sub>3</sub>N<sub>4</sub>) was synthesized as an innovative photocatalyst for the degradation of neutral red dye under visible light. The material was synthesized through a sustainable process involving the calcination of urea, dicyandiamide, and oxalic acid, and its characteristics were evaluated using various techniques, including XRD, FT-IR, UV-Vis spectroscopy, and SEM. Photocatalytic degradation of neutral red was analysed using a custom photoreactor under visible light. The results demonstrated that O-doped g-C<sub>3</sub>N<sub>4</sub> exhibited enhanced photocatalytic efficiency compared to pure g-C<sub>3</sub>N<sub>4</sub>, reducing the recombination of electron-hole pairs and effectively degrading the dye. Adsorption kinetics followed a pseudo-2nd-order model, while adsorption isotherms suggested that the Langmuir model best described the adsorption process, indicating monolayer adsorption. The maximum adsorption capacity of O-doped g-C<sub>3</sub>N<sub>4</sub> for neutral red was 9.643 mg g<sup>-1</sup>, surpassing pure g-C<sub>3</sub>N<sub>4</sub>.

Kinetic studies indicated that the adsorption of neutral red onto OCN-UD primarily followed a pseudo-2nd-order model, demonstrating chemical adsorption processes.

A systematic investigation was then conducted to analyze the composition of the AuPd bimetallic dendrites and the effects of preparation conditions on their structure and catalytic performance. The AuPd alloy dendrites were characterized through various techniques, including scanning electron microscopy, transmission electron microscopy, X-ray energy scattering spectroscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. The results showed that the Au:Pd ratio in the AuPd alloy dendrites closely matched the initial feeding ratio. The catalytic activity and stability of the AuPd alloy dendrites towards 4-nitrophenol reduction were remarkably higher compared to those of the single metal Au and Pd nanocatalysts. Specifically, the Au<sub>1</sub>Pd<sub>1</sub> alloy dendrites exhibited the highest catalytic reduction activity for 4-nitrophenol, with a reaction rate constant of 1.05 × 10<sup>-2</sup>. Moreover, the stability of the Au<sub>1</sub>Pd<sub>1</sub> alloy dendrites was also examined. The results demonstrated that the catalytic stability of the Au<sub>1</sub>Pd<sub>1</sub> alloy dendrites did not experience a significant decrease even after five cycles of operation.</p>","PeriodicalId":23367,"journal":{"name":"Turkish Journal of Chemistry","volume":"49 2","pages":"191-203"},"PeriodicalIF":1.3,"publicationDate":"2024-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12068668/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144034034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
