HCs can store Na ions between stacked sp<sup>2</sup>-layers of carbon and micropores. In this work, hard carbons are synthesized from 1 M, 2 M, 3 M, 4 M, and 5 M dextrose solutions by hydrothermal synthesis followed by high-temperature calcination at 1100 °C in an argon atmosphere. Among all hard carbons derived from different concentrations of dextrose solutions, hard carbon derived from 3 M dextrose solution delivers superior electrochemical performance compared to other hard carbons. Hard carbon derived from 3 M dextrose solution (DHC-3 M) provides an initial reversible capacity of 273 mAh g<sup>−1</sup> with a capacity retention of 82% at the end of 100 charge–discharge cycles at 30 mA g<sup>−1</sup>. Further, high-rate charge–discharge cycling at 200 mA g<sup>−1</sup> shows an initial capacity of 200 mAh g<sup>−1</sup> and retains over 61% capacity at the end of 500 cycles. The improved capacity of DHC-3 M is due to the higher d-spacing value and more disorderness, which improve the plateau region capacity due to the intercalation of Na<sup>+</sup> in the carbon matrix. Besides, 3 M dextrose-derived hard carbons are less agglomerated than other concentrations and show less charge transfer resistance before and after cycling, resulting in improved electrochemical performance.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"29 5","pages":"1829 - 1840"},"PeriodicalIF":2.6,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143821998","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 cellulose fiber was modified with carbon nanotubes and reduced oxide graphene to decrease its electron transfer resistance and ohmic resistance. Due to their low resistance, the bioelectrodes display high electrocatalytic efficiency of glucose oxidation and oxygen reduction. The biosensors are assembled by packaging the bioanodes and gel electrolytes together. The assembled biosensors have a low limit of detection (6.7 µM) and a wide linear range (0.02–0.5 mM). The great sensing performances are strongly associated with the location of bioanodes and biocathodes. The outer biocathode protects the central bioanode that comes from oxygen and ensures the structural integrity of the device during bending cycles. It also reduces the damage caused by the washing. The biosensor also exhibited selectivity, repeatability, and great stability in different pHs and during long-term storage. Finally, the average recoveries in real sweat are 104.9 to 106.0%.

Electrochemical impedance spectroscopy (EIS) confirmed this improvement, showing a decrease in charge transfer resistance (Rct) from 0.225 kΩ for SPCE to 0.125 kΩ for SPCE-AuNPs. Under optimized conditions utilizing differential pulse voltammetry (DPV), the sensor exhibited a linear range of 0.4 to 88.0 μmol L<sup>−1</sup>, a limit of detection of 0.12 μmol L<sup>−1</sup>, and a limit of quantification of 0.4 μmol L<sup>−1</sup>. The developed method was applied to determine CPX in water and pharmaceutical formulation samples, achieving excellent recovery values ranging from 96 to 104%.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"29 3","pages":"901 - 914"},"PeriodicalIF":2.6,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143430835","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}
