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.</p><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}

This issue is exacerbated by industrial effluents containing hazardous organic pollutants and dyes such as crystal violet (CV) and methyl orange (MO), posing significant environmental threats. This study introduces a novel approach utilizing chitosan microsphere-based iron–strontium–zinc oxide photocatalysts aimed at addressing the decontamination of these organic dyes. 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.

However, experimental parameters have to be chosen carefully when systems of different complexity are compared. In order to characterize UHV-based model systems, we use a highly sensitive sniffer setup which allows us to investigate the catalytic activity by combining three different measurement modes: temperature-programmed desorption, continuous flow, and pulsed-reactivity experiments. In this article, we explore the caveats of quantifying catalytic activity in UHV on the well-studied and highly defined reference system of CO oxidation on Pt(111), which we later compare to the same reaction on Pt₁₉ clusters deposited on Fe₃O₄(001). We demonstrate that we can apply fast heating ramps for TOF quantification, thus inducing as little sintering as possible in the metastable clusters. By changing the reactant ratio, we find transient reactivity effects that influence the TOF, which should be kept in mind when comparing catalysts. In addition, the TOF also depends on the surface coverage that itself is a function of temperature and pressure. At a constant reactant ratio, in the absence of transient effects, however, the TOF scales linearly with total pressure over the entire measured temperature range from 200 to 700 K since the reaction rate is dependent on both reactant partial pressures with temperature-dependent reaction order. When comparing the maximum TOF at this particular reactant ratio, we find a 1.6 times higher maximum TOF for Pt₁₉/Fe₃O₄(001) than for Pt(111).
