In this study, biochar derived from <i>papaya seed</i> biomass via slow pyrolysis was investigated for its efficacy in removing organic dyes from aqueous solutions. Both biochar and chemically functionalized biochar were comprehensively characterized using XRD, FTIR, XPS, BET surface area analysis, and SEM/EDS to elucidate their structural, morphological, and surface properties. The adsorption performance was assessed using methylene blue (MB), rhodamine B (RhB), malachite green (MG), and methyl orange (MO) as model contaminants, with particular attention to adsorption kinetics and equilibrium behavior. The unmodified biochar exhibited moderate adsorption capacities, primarily driven by π − π interactions and a limited number of functional groups, achieving removal efficiencies of 55.5, 97.8, and 12.9% for MB, MG, and RhB, respectively, while MO showed negligible adsorption. Remarkably, chemical functionalization with KMnO₄ significantly enhanced biochar performance, increasing surface area and functional group diversity. This modification enabled the complete removal (100%) of MB and MG within six minutes, alongside substantial improvements for RhB and MO, achieving 100 and 88% removal, respectively. Adsorption kinetics followed a pseudo‒second‒order model (<i>R</i>² &gt; 0.99), indicating chemisorption as the dominant mechanism, while Langmuir isotherms (<i>R</i>² = 0.993 − 0.999) suggested monolayer adsorption. Additionally, the intraparticle diffusion model highlighted the synergistic contributions of surface interactions and pore diffusion to overall adsorption efficiency. These findings establish chemically functionalized papaya seed biochar as a highly efficient, low‒cost adsorbent for dye removal, underscoring its potential for environmental remediation. The innovative utilization of papaya seed biomass not only adds value to agricultural waste but also advances sustainable water treatment strategies, reinforcing its significance in environmental science and engineering.</p></div>","PeriodicalId":646,"journal":{"name":"Journal of Materials Science: Materials in Electronics","volume":"36 11","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10854-025-14725-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The barrier height (<i>Φ</i>_b) and ideality factor (<i>n</i>) values of the Schottky contact were determined from the current–voltage (<i>I</i>–<i>V</i>) measurements and found to be 0.29 eV and 2.71 at 125 K and 0.93 eV and 1.04 at 400 K, respectively.

From Cheung’s plot, the series resistance (<i>R</i>_s) was found to be reduced with the increase in temperature. Barrier inhomogeneity has been elucidated using the thermionic emission theory based on the assumption of Gaussian distribution of barrier heights.

To address these challenges, we designed a three-phase Fe₃O₄@C/MnO nanocomposite using an integrated hydrothermal precipitation strategy followed by controlled thermal treatment. The initial discharge capacity of the Fe₃O₄@C/MnO negative electrode at 50 mA g⁻¹ was 1322.90 mAh g⁻¹, which exceeded the theoretical capacity obtained through the interfacial lithium storage mechanism. What's more, after 170 cycles at 200 mA g⁻¹, the capacity can still be maintained at 1042.26 mAh g⁻¹, which is a capacity retention rate of 125.37% compared with the first cycle capacity. This excellent performance stems from the heterogeneous interfacial engineering stabilization and enhanced reaction kinetics of the active materials. The carbon matrix limited the volume change of Fe₃O₄ while maintaining the structural integrity, and the compressive stress generated by MnO nanoparticles alleviated the aggregation of Fe₃O₄. Finally, the built-in electric field generated by the charge redistribution at the interface accelerates the ion/electron transport.
