In this article, we demonstrate the synthesis of sea-urchin-like Bi2S3 combined with MoS2 hierarchical nanoflowers via a hydrothermal route for electrochemical sensing of Flufenamic acid (FMA). FMA is one of the non-steroidal anti-inflammatory drugs (NSAIDs) which endangers human health. The Bi2S3/MoS2 composite's formation was confirmed by various characterizations via microscopic and spectroscopic techniques. The synergistic effect between the two metal sulfides improves electron transport and enables more active sites. Under optimal conditions, the resultant nanocomposite exhibits a high sensitivity value (0.44 μA μM−1 cm−2), a reasonable limit of detection (0.009 μM), and a broad linear range (0.01 – 453 μM). Furthermore, the electrochemical detection of FMA in biological samples was achieved with good reliability and decent recovery.</div>","PeriodicalId":100233,"journal":{"name":"Chemistry of Inorganic Materials","volume":"1 ","pages":"Article 100006"},"PeriodicalIF":0.0,"publicationDate":"2023-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49730442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biodiesel synthesis from animal fats and edible vegetable oils via transesterification over homogeneous catalysts is recently taken into account of untenable by the emerging biofuel industries, particularly by virtue of food vs. fuel counteraction, economic and environmental challenges blended with the feedstocks as well as catalytic systems, respectively. Therefore, present efforts concern with the preparation of a novel PTSA-Si catalyst and its relevance for biodiesel synthesis from non-food castor oil. It has been manifested from the experimental outcomes, the most relevant reaction parameters are, 5% PTSA-Si (w/w), 65 °C reaction temperature, 1:11 O:M molar ratio and 10 h reaction time for 98.56% biodiesel yield. The PTSA-Si was appropriately analyzed using FT-IR, SEM, XRD, BET, TGA-DTA and TPD-NH3 analysis. Since, castor oil and castor biodiesel were analyzed using FT-IR, 1H &13C NMR analysis. Besides, biodiesel physico-chemical properties were predicted and associated with ASTM fuel standards.</div>","PeriodicalId":100233,"journal":{"name":"Chemistry of Inorganic Materials","volume":"1 ","pages":"Article 100005"},"PeriodicalIF":0.0,"publicationDate":"2023-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49707242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
