Biomass-based micropore carbon synthesis; Tamarind wood (Tamarindus indica), Mahogany (Swietenia mahagoni), teak (Tectona grandis), and coconut shell (Cocos nucifera)

Eco-friendly microporous carbon has been successfully synthesized from biomass, namely tamarind wood (Tamarindus indica), mahogany (Swietenia mahagoni), teak (Tectona grandis), and coconut shell (Cocos nucifera). Synthesis uses the carbonization method at a temperature of 600°C for 45 minutes and is washed in an ultrasonic cleaner for 6 hours. Micro-porous carbon powder has a primary molecular bond of C=C and a small amount of C=N, C-H, and C=O as a consequence of the nutrient content and heating process according to the results of the FTIR test, and is in the rGO phase with a reflection plane (002) in the amorphous carbon graphite structure according to test results using XRD. Microporous carbon with rGO-phased microscale with a mean particle size of ~6.04 μm, respectively, tamarind wood (8.07 μm), mahogany (3.65 μm), teak (4.41 μm), and coconut shell (3,90 μm) with morphology in the form of a porous plate according to the results of observations by SEM.
