Recently, there has been a growing interest in Prussian blue-type coordination polymers due to their inexpensive nature, chemical stability, and simple synthesis using non-toxic metals that are prevalent in the earth. The results present a straightforward technique for effectively altering the surface of CNT using cobalt-iron-based prussian blue (CoFe-PB). The procedure led to a significant increase in the removal of crystal violet (CV) from water relative to the bare CNTs. The maximum removal efficiency (about 93 %) of CV dye was obtained at pH 6 with fast saturation time (15 min). The use of the coating approach yields a core–shell structure consisting of CNT as the core and a CoFe-PB shell. The CoFe-PB shell, with a thickness of 10–15 nm, forms a highly conformal coating that completely covers the CNT. The high conformance of the coating is considered an essential characteristic for its strong adsorption performance.

{"title":"Enhanced solar Photocatalysis: Zinc oxide modified Yb2Zn-TiO6 doped g-C3N4 heterostructures for bromothymol blue mineralization and bacterial inhibition","authors":"Karma M. Albalawi","doi":"10.1016/j.jscs.2024.101835","DOIUrl":"https://doi.org/10.1016/j.jscs.2024.101835","url":null,"abstract":"<div><p>A new composite material, ZnO/Yb<sub>2</sub>Zn-TiO<sub>6</sub>@g-C<sub>3</sub>N<sub>4</sub> has been synthesized by simple hydrothermal process. This composite has been characterized using various material characterization techniques and was found to have a heterojunction amongst Yb<sub>2</sub>Zn-TiO<sub>6</sub> and g-C<sub>3</sub>N<sub>4</sub>, leading to higher light absorption and poorer charge carrier recombination rates. Furthermore, the evaluation of the charge carrier density revealed that the incorporation of small sized ZnO (40 nm) into Yb<sub>2</sub>Zn-TiO<sub>6</sub>@g-C<sub>3</sub>N<sub>4</sub> led to heightened disintegration of the photoinduced charge carriers. This observation implies that the presence of said metal oxide enhances the photocatalytic performance by greatly promoting the effective separation of charge carriers for various applications. When tested with bromothymol blue, the 20 wt% ZnO/Yb<sub>2</sub>Zn-TiO<sub>6</sub>@g-C<sub>3</sub>N<sub>4</sub> composite showed a photodegradation rate several times greater (98 %) than individual ZnO, C<sub>3</sub>N<sub>4</sub> and Yb<sub>2</sub>Zn-TiO<sub>6</sub>, respectively. The degradation efficiency of the ZnO/Yb<sub>2</sub>Zn-TiO<sub>6</sub>@g-C<sub>3</sub>N<sub>4</sub> nanostructure in the absence of light was 24 %. The increased photoactivity of the composite material is due to the efficient separation of charge carriers and also due to the high redox capabilities resulting from the heterojunction. The composite also demonstrated stable photocatalytic performance over five cyclic runs and was effective in treating real printed ink wastewater. Furthermore, ZnO/Yb<sub>2</sub>Zn-TiO<sub>6</sub>@g-C<sub>3</sub>N<sub>4</sub> was found to have excellent antibacterial properties in opposition to <em>Escherichia coli</em>, (Inhibition = 16(±0.2) mm) as well as <em>Bacillus subtilis</em> (Inhibition = 22(±0.3) mm). The MIC of the said nanomaterials against <em>Escherichia coli</em> as well as <em>Bacillus subtilis</em> were 50 µg/mL and 30 µg/mL respectively. The detailed explanation of the photodegradation mechanism was also provided. The use of this composite material can help to reduce the harmful effects of contaminants and microbes in aquatic environments and promote environmental sustainability.</p></div>","PeriodicalId":16974,"journal":{"name":"Journal of Saudi Chemical Society","volume":"28 3","pages":"Article 101835"},"PeriodicalIF":5.6,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1319610324000309/pdfft?md5=bb6ef04e892315a4b2e47b4588c57b38&pid=1-s2.0-S1319610324000309-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140113695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
