These nanocomposites enhance the photocatalytic activity of TiO₂ in visible light, suppress the e^-/h⁺ rearrangement, and enhance their bactericidal properties. This review proposes a bibliometric analysis that elucidates research trends, and important topics on contaminant degradation, analyzes the advantages and limitations of different synthesis techniques (solvothermal, photochemical reduction, sol-gel, and others), their properties to produce Ag/TiO₂, and their potential for pollutant degradation. Thus, depending on the technique chosen, Ag doping of TiO₂ can offer high stability, recyclability for more than 3 cycles, customized morphologies and sizes, among others. Applications of Ag/TiO₂ include wastewater treatment, antibacterial surfaces, food packaging, implants, and others. Advances in the synthesis of Ag/TiO₂ photocatalysts offer excellent photocatalytic degradation, between 80 % and 100 %, for organic dyes, hormones, pharmaceuticals, pesticides and other emerging pollutants. Ag/TiO₂ photocatalysts show superior degradation rates compared to pure TiO₂, with some achieving up to 99 % pollutant removal. The bibliometric analysis performed by Methodi Ordinatio, classifying 267 articles, reveals a foundation of relevant articles, around 35 % of articles published on these topics were published between 2019 and 2021. A complete cost analysis of Ag/TiO₂ is considered to determine the feasibility for pilot and large-scale experimentation. These nanocomposites offer a promising solution to address the growing concern about emerging pollutants, disinfection of water, and in the inactivation of pathogenic microorganisms.</div></div>","PeriodicalId":101196,"journal":{"name":"Sustainable Chemistry for the Environment","volume":"8 ","pages":"Article 100177"},"PeriodicalIF":0.0,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142533976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Investigation of the oil sorption behaviors of the adsorbents involved batch sorption experiments. The SEM analysis revealed improvements in the surface morphology of the acetylated pods. The BET surface area increased from 265.2 m²/g to 335.0 m²/g after acetylation. The FTIR spectra of the oil-treated pods showed that the acetylated pods adsorbed more oil than the native pods. The Langmuir isotherm best described the sorption equilibrium for the adsorbents. Kinetic analysis showed that the sorption processes conformed to the pseudo-second-order model, and were controlled by film diffusion alone or in conjunction with other mechanisms.
