“…Tectona (Tectona grandis) is a genus of Lamiaceae family, extensively utilized for home stuffs, indoor floor boards, sculpturing, boat decks, cabinetry, and so on. , It possesses cellulose (∼47.5%), lignin (∼29.9%), and carbon (∼49%), representing a favorable carbon natural source and has been widely considered in biomass utilization research areas. − Thus, the large quantity of lignocellulosic biomass in dead teak leaves as raw carbon precursors for the production of ACs is a desirable candidate for the removal of dyes, production of biogas, and wastewater treatment. − …”

In this work, the preparation of porous carbon obtained from teak (Tectona grandis) leaves is reported and used for supercapacitors (SCs). The teak leaf carbon (TLC) was prepared using the biowaste as the carbon source precursors by NaOH activation and pyrolysis at 700−1000 °C under a nitrogen atmosphere. The crystallinity, structural features, textural properties, and thermal stability of TLCs were characterized by a variety of state-of-the-art techniques. Further electrochemical (EC) measurements, such as cyclic voltammetry, electrochemical impedance spectroscopy, and galvanostatic charge−discharge using a three-electrode setup, were done. The TLC-900 has micro-and mesoporous materials with large surface areas and pore volumes as high as 1692.6 m 2 g −1 and 0.86 cm 3 g −1 , respectively. Also, they exhibit remarkable EC and capacitive properties, achieving a maximum high specific capacitance (C sp ) of 310 F g −1 with a current density of 1.0 A g −1 in a 3.0 M KOH solution. Notably, TLC-900 attained a EC stability, achieving 123% retention in the same electrolyte after 10,000 cycles at a current of 1.0 A g −1 . As a result, the fabricated device displayed a maximum energy density of 24 W h kg −1 and power density of 1818 W kg −1 at a current density of 10 A g −1 . These outstanding EC behaviors, oxygen-containing functional groups, and structural characteristics of this porous carbon material indicate that TLCs are attractive for the fabrication of future large-scale industrial SCs.

“…Mohammed and Tanweer’s review, in 2018, concerning the utilization of wood biomass as a sustainable precursor for AC production, revealed that these precursors allow adsorbents with well-developed physical and textural characteristics to be obtained [ 17 ]. The use of Tectona Grandis subproducts for the production of ACs was only referenced by a few works [ 10 , 18 , 19 , 20 , 21 ]. However, the present study is the first time that Tectona Grandis waste was used to obtain ACs by chemical activation with KOH and K 2 CO 3 .…”

This work presents a first approach concerning the valorization of Tectona Grandis tree by-products, from East Timor through their transformation into high activated carbon (AC) by chemical activation with KOH and K2CO3. The better ACs, Teak-KOH-1-1-700 and Teak-K2CO3-1-2-700, presented a high ABET (995 and 1132 m2·g−1) and micropore volume (0.43 and 0.5 cm3·g−1), respectively. Both ACs were tested on the removal of four pesticides, from the liquid phase. Both ACs performed better than existing commercial types, presenting a maximum adsorption capacity of 1.88, 1.67, 1.10 and 0.89 mmol·g−1, for 4-chloro-2-methylphenoxyacetic acid, 2,4-dichlorophenoxyacetic acid, diuron and atrazine, respectively. Pesticide adsorption from diluted and concentrated solutions confirms that diffusion is the limiting factor. The possibility of implementing a production unit for ACs in East Timor is very promising for that country. It presents an opportunity for job creation, biomass waste reduction and a contribution to environmental sustainability, thereby following the principles of a circular economy.

High quality activated carbon was successfully produced from Tectona grandis sawdust by chemical activation using potassium chloride and sodium thiosulphate in a ratio of 1:1.5:1. Surface characterization of sawdust and activated carbon showed the presence of several functional groups such as hydroxyl, ketones, phenols, carboxylic acids, aldehydes and aryl halide together with the heterogeneous surface and extensive porous network as depicted by morphological characterization. It was found that the per cent yield by mass of Tectona grandis sawdust was 52% (SD ± 0.41%). The content of fixed carbon (67.3%) and volatile matter (13.7%) in T. grandis sawdust signifies the ease with which it can be ignited and oxidized. The x‐ray diffraction analysis of activated carbon prepared from T. grandis sawdust indicated amorphous behavior of activated carbon. In the present work, activated carbon possesses 8.76 pH zero‐point charge, 1270 m2/g BET surface area, 0.673 cm3/g total pore volume and 0.42 g/cm3 bulk density.
