By employing a simple ultrasonic process, the OFe-GO catalyst was successfully prepared through the immobilization of OFe onto the GO support. Various characterization methods were used to fully explore the crystalline character, morphological surface, chemical state and magnetic property of the prepared catalyst substances. In the presence of hydrogen peroxide (H2O2) as a green oxidant, the catalytic performance of RhB degradation using the proposed magnetic catalyst was explored. The experimental factors affected on the Fenton performance such as solution pH, catalyst concentration and H2O2 concentration were evaluated and optimized. Using the established protocol, 50 mg mL−1 of RhB can be completely at 15 min reaction time. Additionally, the used OFe-GO catalyst can be regenerated without losing the degradation performance for at least five cycles. Because of notable catalytic efficiency, fast degradation, and operational stability, the OFe-GO can be considered as an effective and separable catalyst for decolorization of dye-containing wastewater.<h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":801,"journal":{"name":"Topics in Catalysis","volume":"22 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140938121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A non-enzymatic amperometric sensor based on nanostructured porous Cu-Au electrocatalyst martial was designed and employed for lactate determination. For this purpose, the bimetallic surface was successfully coated on the glassy carbon electrode (GCE) using co-electrodeposition of copper and gold ions. The Cu-Au alloy proved to be an effective interface for the direct electrochemical oxidation of lactate. The Cu-Au modified GCE exhibits excellent lactate sensing capabilities thanks to the excellent conductivity of gold element in bimetallic material and high surface area of the porous Cu-Au alloy. In phosphate buffer solution, this novel electrochemical lactate sensor demonstrates a linear response to lactate within the concentration range of 20 to 2000 µM. The detection limit (based on S/N = 3) of the assay was estimated to be 5 µM. The established electrochemical sensing protocol is a highly selective device for the analysis of lactate in biological fluids. The lactate level in saliva samples was successfully quantified before and after exercise of athletes using the recommended strategy. The present non-enzymatic sensor offers a convenient, fast, cost-effective, and effective protocol for lactate measuring in clinical diagnosis applications.<h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":801,"journal":{"name":"Topics in Catalysis","volume":"22 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140938503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The synthesis of iron–strontium–zinc oxide was performed via co-precipitation method followed by its characterization using various techniques. The resulting CS-Fe2SrZnO4 microspheres exhibited a sleek morphology with an average diameter of 917 μm, featuring the confirmed presence of iron, strontium, and zinc oxide as ascertained by EDX analysis. With a bandgap of 1.24 eV, this material showcased remarkable efficacy in degrading CV and MO dyes under solar light irradiation. Optimized conditions were identified to attain maximum degradation efficiency for both dyes. The findings reveal that the maximum degradation achieved for MO and CV was 94% and 98%, respectively, at the optimized conditions (time; 60 min, catalyst dosage; 0.1 g, concentration 20 ppm, pH; 6 for MO and 8 for CV). The statistical analysis was also performed which supported the obtained results. The kinetics study showed that the degradation followed pseudo-first order kinetics with R2 value of 0.96.

The concept of lignocellulosic biomass conversion into value-added chemicals or materials is gaining in importance worldwide as a means of replacing conventional petrochemical resources for environmental sustainability. The production of biofuels such as bioethanol from lignocellulosic biomass consists of three main processes: pretreatment, enzymatic saccharification, and fermentation. As lignocellulose exhibits a highly recalcitrant structure, effective pretreatments are required for its deconstruction, making carbohydrates accessible for microbes to produce valuable bioproducts. These carbohydrate polymers (cellulose and hemicellulose) are then transformed into free monomeric sugars by the process of saccharification. Saccharification, especially enzymatic hydrolysis, is the crucial step for achieving lignocellulose bioconversion. Several strategies have been developed for diminishing biomass recalcitrance, ultimately improving the efficiency of product conversion, and reducing overall process costs. Some of these approaches include consolidated bioprocessing, consolidated bio-saccharification (on site), as well as simultaneous saccharification and fermentation, and separate hydrolysis and fermentation (off site). This review provides a detailed overview of current approaches to on-site and off-site saccharification and highlights the key factors for obtaining bioproducts from lignocellulosic feedstock via economically feasible bioconversion processes.
