Among these dyes, malachite green (MG) is of particular concern because of its carcinogenic, mutagenic, and teratogenic effects, as well as its widespread use in aquaculture and textile industries. Existing treatment methods, such as coagulation, membrane filtration, and photocatalysis, suffer from high operational costs, secondary waste generation, or limited scalability. Adsorption remains a promising alternative, especially when low-cost, sustainable adsorbents derived from agricultural waste are used. This study explores the potential of carbonized wild sugarcane (<em>Saccharum spontaneum L.</em>), an underutilized lignocellulosic biomass, as a sustainable adsorbent for MG removal from aqueous solutions. Two forms were investigated: untreated (CWSC-U) and acid-treated (CWSC-A). Fourier Transform Infrared (FTIR) spectroscopy confirmed the successful surface modification, showing the removal of native functional groups during carbonization and the reintroduction of oxygen-containing groups after acid treatment. CWSC-U exhibits a fibrous and fragmented carbon structure with hierarchical porosity, whereas CWSC-A displays a more intricate and well-developed porous network. Elemental analysis reveals that CWSC-A possesses a markedly higher carbon concentration and a lower content of inorganic impurities. Batch adsorption experiments evaluated the effects of initial dye concentration, adsorbent dosage, pH, and temperature. Analysis of Variance (ANOVA) identified acid treatment as the most influential factor in improving MG removal, followed by adsorbent dosage, pH, and temperature, with notable interaction effects among variables. CWSC-A demonstrated significantly higher adsorption capacity and stability across a broad pH and temperature range, outperforming CWSC-U, which showed greater sensitivity to operating conditions. This enhanced performance was attributed to CWSC-A’s enriched surface functionality, enabling stronger physisorptive and chemisorptive interactions, in contrast to the primarily physisorptive behavior of CWSC-U. Optimization identified optimal conditions (30 mg/L MG, 8.0 g/L adsorbent dosage, pH 3, 60 °C), under which CWSC-A achieved a validated removal efficiency of 94.90 %, compared to 74.36 % for CWSC-U. Thermodynamic analysis indicated more spontaneous and energetically favorable adsorption on CWSC-A. Post-adsorption FTIR further supported the distinct mechanisms, with CWSC-A involving specific functional group interactions. When benchmarked against other biomass-derived adsorbents, CWSC-A exhibited competitive or superior performance. Overall, acid treatment significantly enhances the adsorption efficiency and versatility of carbonized wild sugarcane, establishing CWSC-A as a promising, low-cost, and eco-friendly material","PeriodicalId":100958,"journal":{"name":"Next Materials","volume":"9 ","pages":"Article 101004"},"PeriodicalIF":0.0,"publicationDate":"2025-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144704254","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}

Therefore, nanotechnology has been explored as a possible means of improving various renewable energy systems, as it makes energy generation, storage, and conversion more efficient at the nanoscale. Nanomaterials like carbon nanotubes, metal nanoparticles, graphene, and metal oxides can significantly improve the efficiency of solar cells, fuel cells, and other renewable technologies. While lowering weight, graphene and carbon nanotubes enhance the electrical conductivity and durability of battery electrodes. Fuel cells and solar hydrogen generation systems benefit from the enhanced charge transfer and reaction kinetics provided by nanostructured metal oxides such as TiO₂ and CeO₂. The high surface area and optical absorption properties of nanomaterials enable more efficient sunlight harvesting in solar cells, as nanoparticle coatings on solar cell surfaces improve light trapping and anti-reflection capabilities. Nanotechnology also enables advanced energy storage through improved batteries, supercapacitors, and hydrogen storage systems. Batteries with nanoparticle-enhanced electrodes exhibit higher power density and faster charging capabilities compared to conventional batteries. Supercapacitors fabricated with nanomaterials demonstrate high capacitance and cycling stability. The objective of this research is to investigate the ability of nanotechnology to enhance the performance and efficiency of renewable energy systems. Through comprehensive analysis of existing studies, new developments and key applications requiring further research are identified. Nanotechnology presents immense potential for advancing renewable energy technologies through the unique properties of nanomaterials. By improving things like electrical conductivity, surface area, catalytic activity, and optical absorption at the tiny nanoscale, we can greatly boost how we generate, store, and use energy.

Comprehensive characterization revealed that the 0.2 M Al-doped TiO₂ exhibited enhanced crystallinity and dye loading with improved light absorption, owing to its larger surface area and uniform porosity. Electrochemical impedance spectroscopy and Mott-Schottky analysis confirmed that Al doping improved conductivity, charge carrier separation, and reduced recombination rates, particularly at the optimal doping concentration of 0.2 M. In agreement with the experimental results, theoretical calculations employing density functional theory (DFT) demonstrated that Al doping narrowed the bandgap and introduced donor-like states, improving visible-light-driven applications. Photovoltaic performance assessments revealed a peak power conversion efficiency (PCE) of 1.34 % for DSSCs fabricated with the 0.2 M Al-doped TiO₂ photoanode, outperforming pure and other doped samples.
