In addition, the developing industry pollutes existing water resources. This situation negatively affects all living things on earth. In this study, the biosorption process of cationic dye methylene blue (MB), which was selected as a model dye compound from residual water, and sunflower tray biosorbent was discussed. It was seen that the amorphous structure of the sunflower tray was similar to the hexagonal structure. The process parameters were investigated to reach the highest biosorption efficiency. The highest efficiency (99%) was achieved at pH 6, biosorbent dose 10 g/L, dye concentration 10 mg/L and temperature 20 °C. It was determined that the biosorption process with an exothermic reaction was compatible with the Langmuir isotherm (R² = 0.96) and the pseudo-second-order (PSO) kinetic model (R² = 0.99). q_max was calculated as 117.6 mg/g. ΔG values suggested that the interaction between the sunflower tray and MB molecules was not spontaneous.</p></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"79 3","pages":"1427 - 1438"},"PeriodicalIF":2.2,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143667966","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}

Traditional photocatalysts, such as TiO₂, ZnO, and Fe₂O₃, often exhibit high crystallinity and photosensitivity, poor surface adsorption capacity, and limited visible-light responsiveness, leading to suboptimal photocatalytic efficiency. rGO enhances the photocatalytic performance of these materials by reducing the band gap, increasing electron–hole (e-/h⁺) separation rates, and expanding specific surface areas. Functionalizing rGO with amino groups improves the mechanical and thermal stability of hybrid nanocomposites, thereby maintaining a higher surface area and enhancing catalyst stability. Composites like rGO-ZnO, CuS-frGO, and AgBr@GN exhibit superior photocatalytic activity in degrading organic pollutants. This also review investigated the design and performance enhancements of rGO-based semiconductor nanocomposites, discussing how rGO improves electron mobility, reduces electron–hole recombination, and facilitates interactions with pollutants through π-π interactions. Fine-tuning rGO content and structure has led to significant improvements in photocatalytic efficiency, making these composites promising for commercial water purification. However, challenges such as synthesis methods, environmental impact, and real wastewater testing remain. Continued research and development are crucial for addressing these challenges and realizing the full potential of rGO-based photocatalysts in practical water purification systems.</p></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"79 2","pages":"637 - 654"},"PeriodicalIF":2.2,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143583571","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}

Titanium dioxide (TiO₂) is one of the most efficient and non-toxic photocatalysts used in water treatment. The main obstacle facing TiO₂ being applied on a large scale is requiring high light energy, mainly in the ultraviolet region (only 5% of sunlight), to activate the photocatalysts. Lowering the band gap of TiO₂ nanoparticles makes them easily activated by sunlight. Oxygen vacancies (OVs) or Ti³⁺-rich TiO₂ can have a lower band gap and enhance performance. Titanium hydroxide was calcinated in a vacuum to obtain modified TiO₂ and then immobilized in chitosan hydrogel as a great self-healable supporter with high availability and antimicrobial behavior. Characterization was done by using XRD and UV–visible absorbance spectroscopy. Photocatalytic studies were constructed on C.I. Acid Blue 324 as a model for dyes and on Pb, Cu, Cd, and Ni as models for heavy metals using modified-TiO₂ and white-TiO₂ encapsulated in chitosan beads separately under sunlight. The modified TiO₂chitosan composite has a higher degrading ability than the white one.
