In this study, we synthesized pure ZnO and Co-doped ZnO (Co/ZnO) photocatalysts through a simple coprecipitation approach. UV-visible spectroscopy (UV-Vis), fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and energy-dispersive X-ray analysis (EDAX) were among the analytical methods used to certainly evaluate the photocatalysts. XRD patterns confirmed that the Co-ZnO sample exhibited a single-phase structure also exhibits crystallite size were 20 nm. Co, Zn, and O components were confirmed to be present in the synthetic material by EDAX analysis. FESEM imaging revealed the nanoparticle spherical like morphology of the Co-ZnO photocatalyst, while FTIR spectra provided information on the material’s chemical bonds. The band gap was measured using UV-Vis spectroscopy, with Co-ZnO nanoparticles showing a band gap of 2.83 eV. The synthesized photocatalysts were applied to degrade methylene blue, methyl orange dye and tested for antimicrobial properties. Results indicated that the optimized Co doped ZnO sample achieved higher photocatalytic performance under sunlight, with 86% degradation of methylene blue dye within 120 min. Additionally, the photocatalyst displayed antimicrobial activity against Salmonella typhi, Enterococcus, and Candida parapsilosis.","PeriodicalId":761,"journal":{"name":"Russian Journal of General Chemistry","volume":"95 8","pages":"2152 - 2163"},"PeriodicalIF":0.8,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145028325","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}

Conventional plastics have been derived predominantly from non-renewable fossil fuels, like crude oil or natural gas. Worldwide production of plastic is growing significantly every year; while the amount of plastic that has been recycled effectively is quite low, forcing a negative impact on the environment and sustainability. Larger plastic items decompose into smaller particles over time known as microplastics. These microplastics can enter the food chain, potentially harming living organisms and posing risks to human health. Conventional plastics also play an important role in greenhouse gas emissions, contributing to climate change. Bioplastics and biocomposites generated from plant sources like starch, cellulose, lignin, pectin, CAN’s based, banana peel, bamboo based etc. are becoming increasingly popular as a sustainable alternative to traditional petroleum-based plastics due to their eco-friendly nature. In addition, the bioplastics and biocomposites were easily recycled and biodegraded completely in the soil within a short span of time. In this review, we discuss the recent developments and innovations from the year 2023 and 2024 in the field of bioplastics, biocomposites and their applications. Special importance will focus on their synthesis from natural sources and their biodegradable nature which make bioplastics a sustainable alternative. The purpose of this study is to investigate the latest progress and the future perspective of biodegradable plastics and their impact on the environment.","PeriodicalId":761,"journal":{"name":"Russian Journal of General Chemistry","volume":"95 8","pages":"1906 - 1923"},"PeriodicalIF":0.8,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145028332","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}

The structure and properties of the supported catalysts were characterized through Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), N2 adsorption-desorption (BET), and thermogravimetric analysis (TGA). In this experiment, Co3O4/g-C3N4 was utilized as the catalyst, H2O2 served as the oxidant, and a co-crystal solvent [(polyethyleneglycol-200) : (tetrabutylammonium chloride) = 2 : 1] was employed as the extractant for the oxidative desulfurization of model oil. The impact of different loadings, reaction temperatures, oxygen-sulfur ratios, catalyst dosages, and types of sulfides on the desulfurization rate were systematically investigated. The results demonstrate that under optimal conditions of T = 50°C, m(catalyst) = 0.03 g, and n(O)/n(S) = 10, the desulfurization rate of the 30%Co3O4/g-C3N4 catalyst can reach 93.6±0.5% after a reaction time of 75 min. After five cycles of recycling, the catalytic activity of the catalyst exhibited no significant decrease.","PeriodicalId":761,"journal":{"name":"Russian Journal of General Chemistry","volume":"95 8","pages":"1984 - 1997"},"PeriodicalIF":0.8,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145028189","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}

The ligands were characterized with IR and NMR spectroscopy. The influence of aqueous phase pH on the formation of CuL2 complexes and thermal decomposition were studied. Chloroform was chosen as the best extractant. A single extraction with chloroform extracted 98.6–99.3% of Cu(II). The yield of CuL2 was maximum at cL = 0.008 M and did not decompose for 24 hours or more than 45 days after extraction. Maximum light absorption is achieved within 10 minutes. Phase volume ratios of 5:5–115:5 did not affect the recovery. The optimum acidity is in the range of pHopt = 0.3–6.7 (pHform = 2.1–4.7). The molar absorption coefficients are ε480–490 = (4.21–4.26) × 104. Compliance with the fundamental law of light absorption is achieved at cCu(II) = 0.16–18 μg/mL.
