“…This value is extraordinary for supercapacitor electrodes produced from carbon materials based on biomass waste without additional chemical and physical activating substances which are of course very environmentally friendly and low cost. Furthermore, these results can be compared with the performance of other biomass-based carbon electrodes that have been studied previously such as date stone (126.5 F g -1 ) [13], stinky bean seedpod (193 F g -1 ) [14], and torch ginger (285.89 F g -1 ) [15].…”

The increasingly rapid development of environmentally friendly porous activated carbon (AC) materials has attracted the attention of researchers. Moreover, the material can be produced from organic waste which is abundantly available. This time, porous active carbon based on green material (palm frond waste) has been successfully prepared and characterized. The application of more efficient, environmentally friendly and cost-effective, methods and production instrument has been optimized in this research. Integrated pyrolysis with carbonization (N2; 600 °C) and physical activation (H2O; 800 °C) produces activated carbon with a high purity level of up to 80 %. Through reviewing N2 gas absorption, it was confirmed that palm frond AC has a specific surface area of 356 m2 g−1, with a rough morphological structure and very rich surface nanopores. Furthermore, XRD characterization confirmed the purity of carbon through good amorphorosity properties with the presence of two wide peaks at diffraction angles of 22-24° and 42-44°. These findings show that the development and innovation of activated carbon production that is more environmentally friendly and cost-effective from palm frond waste is capable of producing active carbon with extraordinary physical characteristics. This palm tree AC has high potential for developing applications such as as an absorption material in air purifiers and water purifiers. Apart from that, these extraordinary characteristics also make palm frond AC suitable for use as electrode material in components of energy storage devices, supercapacitors with specific capacitance 86 F g−1.

“…Later on, in the ancient age, other applications appeared such as in metallurgy for the smelting of ores in which charcoal was used as a reducing agent or in water purification taking advantage of its adsorption properties after specific activation treatments. Currently, the potential use of pyrolyzed wood as the starting conductive material has mainly found application in the production of anodes in fuel cells , and of supercapacitors for energy storage applications. , However, they have scarcely been applied in the development of electrodes for electroanalytical applications. , Moreover, to the best of our knowledge, they have not been used for the manufacturing of screen-printed electrodes. The present work aims to contribute to the upcycling of wood biomass by investigating the potential of the carbon-based materials obtained from the pyrolysis of wood residues for producing electrodes for sensing applications.…”

Biomass residues from forestry and wood manufacturing contain a high percentage of carbohydrates that can be upcycled to manufacture carbon-based materials of high added value in the context of the circular bioeconomy. This work reports the upscaling of pine, chestnut, and oak wood residues into functional conductive carbon materials applied to the manufacturing of electrochemical sensors. Studies carried out by thermogravimetry, Raman spectroscopy, nitrogen adsorption, and electrochemical measurements revealed a clear correlation between the biomass structure and the electrochemical performance of the resulting carbon material structure. The electrochemical response of the produced carbons appeared to be negatively affected by the wood hemicellulose content but positively correlated with the content of cellulose and lignin. Of the three tested wood wastes, chestnut-derived carbon exhibits the best electrochemical performance, being thus selected as the feedstock to fabricate screen-printed electrochemical devices. Batches of 120 screen-printed devices were prepared from 20 mL of carbon ink obtained from 60 g of chestnut wood wastes. The analytical performance of the fabricated devices was thoroughly assessed in solutions containing representative redox species. Then, devices were applied to the detection of heavy metals by well-known anodic stripping voltammetric detection schemes based on the electrodeposition of Bi or Sb onto the electrode surface. Some real water samples were analyzed in the lab, and the values obtained with the screen-printed device sensors are in good agreement with the reference values, within the error limits. These results demonstrate the potential of applying wood residue-derived carbon materials for the manufacturing of electrochemical sensor devices, looking at reducing the carbon footprint of these widespread analytical tools.
