Its earliest uses date back to ancient agricultural practices across the world, where it was used to enrich the soil.

This article provides a description of the main production techniques and their advantages. It offers an overview of the physical and chemical properties, including surface area, porosity, and elemental composition, as well as the factors that influence them. It also reviews different activation methods used to enhance biochar's properties, depending on its intended use. It discusses the applications that are now in use, such as its role in environmental remediation, energy production, and as a catalyst, analysing the possible future applications as well. All of this is realized with a careful examination of nanobiochar, investigating how certain properties, such as surface area and porosity, differ at nanoscale. Materials with a size of less than one hundred nanometers are classified as \"nano\" and tend to behave differently due to the significant increase in surface-to-volume ratio, which leads to the observation of quantum confinement effects.</div></div>","PeriodicalId":100942,"journal":{"name":"Nano Trends","volume":"10 ","pages":"Article 100117"},"PeriodicalIF":0.0,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143942777","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}

Carbon materials serve as excellent hosts for organic guest molecules. In this study, pyrene molecules were incorporated into five different carbon matrices using a low-temperature thermal encapsulation technique, and the resulting materials were evaluated as effective electrodes for electro-osmotic pump (EOP) application. Since pristine pyrene is electrochemically inactive, it was electrochemically oxidized prior to its use in the EOP. The five carbon materials used in this study, super carbon (SC), multi-walled carbon nanotubes (MWCNTs), Ketjen black carbon (KC), activated carbon (AC) and hard carbon (HC) underwent thorough physicochemical characterization. The encapsulation of pyrene within these carbon matrices, followed by the electrochemical oxidation of the guest pyrene molecules to obtain eSCO, eCNTO, eKCO, eACO, and eHCO, was confirmed through spectroscopic and electrochemical studies. An EOP consists of a silica frit sandwiched between two flow-through electrodes. Five EOPs were assembled with eSCO, eCNTO, eKCO, eACO, and eHCO as the active electrode materials. The water pumping performance of all the EOPs was found to be linearly dependent on the applied voltage. The electro-osmotic flux of the EOPs with eSCO, eCNTO, eKCO, eACO, and eHCO was measured at 33.81, 31.48, 31.18, 20.68, and 7.95 mL min⁻¹ V⁻¹ cm⁻², respectively.
