Hydrothermal Treatment to Produce Honeycomb-like Structure of Hierarchical Carbon from Intsia, spp Waste Wood: Preparation and Characterisation | Chapter 7 | New Innovations in Chemistry and Biochemistry Vol. 5

 Hydrothermal treatment of Intsia spp wood waste resulted in the formation of hierarchical carbon structures resembling honeycombs. The goal of this research is to see how hydrothermal and non-hydrothermal activation methods differ in the hierarchical synthesis of carbon. The hydrothermal treatment was created sequentially using ZnCl2 as an activator and H2O2 as an oxidizer. Carbonisation at 700°C under N2 gas (HC-ZH) and oxidation at 350°C in an oxygen stream follow the hydrothermal process (HC-ZH-Ox). XRD, FT-IR, the Boehm method to measure the quantity of oxygenated functional groups (OFGs), the NH3 base gas adsorption method to estimate the total acid amount, and the Surface Area Analyzer (SAA) and SEM were used to examine all carbonised products. XRD study reveals hierarchical carbon with amorphous structure. The content of OFGs was increased by 50.25 percent for carboxylic groups, 354.62 percent for phenolic groups, and 3.9 percent for lactone groups after hydrothermal treatment. The existence of OFGs was established via FTIR analysis. The largest surface area obtained by hierarchical carbon non-hydrothermal (HC-Ox) of 443.5 (m2/g) was produced by hydrothermal treatment, which enhanced acidity by 387.83 percent. The surface area of the HC-ZH-Ox is 232.2 (m2/g). In the samples HC-ZH-Ox and HC-Ox, a SEM picture shows a stacked honeycomb-like structure with varying thicknesses.
