Summary

Nanostructured porous materials are of great interest due to their diversified final applicability. The versatile and tunable properties of porous materials, such as surface area, electrical conductivity, lightweight, and chemical stability, are advantageous for applications in different areas, including biomedicine, aerospace and aircraft technologies, catalytic processes, energy storage, soil remediation, purification of water, and wastewater treatment, among others. The increased number of new technologies for the development of new materials, processes, and composites raise awareness of environmental issues because most of the nanostructured materials are based on synthetic and non-renewable sources. This leads to the search for technological innovations in the development of sustainable materials. Therefore, current research in renewable, biobased, and nanostructured materials is a hot topic in light of a circular economy.
This research topic aims to compile a collection of articles based on renewable nanostructured materials. The scope of interests includes but is not limited to the research areas above.

    Bio-Derived Tannin-Modified Phenolic Carbon Cryogels with Optimized Microstructure for Supercapacitors Application

    Zhiying Lin, Boju Deng, Qianqian Zhang, Jingming Chen, Xinqiang Ye, Yuling Lan, Jiuping Rao, Mizi Fan, Weigang Zhao

    Abstract Bio-derived carbon cryogels have garnered significant interest as promising electrode materials for supercapacitors due to their high specific surface area (SSA), hierarchical porosity, and eco-friendly synthesis methods. In this study, a tannin-modified phenolic hydrogel was synthesized using a sustainable tannin–phenol precursor system and subsequently subjected to three distinct drying methods-freeze-drying (FD), supercritical drying (SCD), and ambient pressure drying (APD)-to systematically evaluate their influence on structural integrity, porosity, and electrochemical behavior. Among these, the sample obtained via freeze-drying (TPUF-FD) maintained the most intact porous network, minimizing structural collapse during sublimation of ice under vacuum. This preservation… More >

    Abstract Here, we report a comprehensive study on the characterization of cotton biomass residue, its conversion into carbon-based materials via pyrolysis, and its application as an electrochemical sensor for ascorbic acid (AA). The compositions, morphologies, and structures of the resulting materials were investigated using XRD, FTIR, TGA, SEM, and EDS. Pyrolysis was carried out in an air atmosphere at different temperatures (300°C and 400°C) and durations (1, 60, and 240 min), leading to the transformation of lignocellulosic cotton residue into carbon-based materials embedded with inorganic nanoparticles, including carbonates, sulfates, chlorates, and phosphates of potassium, calcium, and… More >

    Abstract Biochar, a carbon-rich material derived from the thermochemical conversion of biomass under oxygen-free conditions, has emerged as a sustainable resource for radar-absorbing technologies. This study explores the production of activated biochars from end-of-life wood panels using a scalable and sustainable physical activation method with CO2 at different temperatures, avoiding the extensive use of corrosive chemicals and complex procedures associated with chemical or vacuum activation. Compared to conventional chemically or vacuum-activated biochars, the physically activated biochar demonstrated competitive performance while minimizing environmental impact, operational complexity, and energy consumption. Furthermore, activation at 750°C reduces energy consumption by 14%… More >

    Abstract Radar Absorbing Materials (RAM) are a class of composites that can attenuate incident electromagnetic waves to avoid radar detection. Most carbon allotropes that have the potential to be used as RAM are either carbon nanotubes (CNTs), graphene, carbon black (CB) and ultimately, sustainable porous carbon (SPC). Here, black wattle bark waste (following tannin extraction) was used as a sustainable source to produce SPC made from biomass waste. It was characterized and used as a filler for a silicone rubber matrix to produce a flexible RAM. The electromagnetic performance of this composite was compared with composites… More >

    Abstract Reconstituted wood panels have several advantages in terms of ease of manufacturing, but their shorter life span results in a huge amount of reconstituted wood panels being discarded in sorting centers yearly. Currently, the most common approach for dealing with this waste is incineration. In this study, reconstituted wood panels were converted into activated biochar through a two-step thermochemical process: (i) biochar production using pilot scale fast pyrolysis at 250 kg/h and 450°C; and (ii) a physical activation at three temperatures (750°C, 850°C and 950°C) using an in-house activation furnace (1 kg/h). Results showed that… More >
