Preparation of activated carbon from bamboo using mechanical milling method / Nurul Anis Akmal Zahari

This study aims to prepare activated carbon from bamboo using mechanical milling. Bamboo needs to go through drying, grinding, sieving, milling, and carbonization processes. All of these processes are important to ensure that the activated carbon obtained is of high quality with desirable properties such as high surface area, and enhanced adsorption capacity. The bamboo-derived activated carbon (AC) is then analysed via different analyses such as X-ray diffraction (XRD), Elemental Analyser (EA), and microscope imaging. For XRD and EA, the analysis is to observe the characterization of the bamboo-derived AC that underwent different circumstances, like different durations of milling (i.e. 1 hour and 6 hours) with the same speed of rotation, which is 400rpm, and different furnace temperatures when the carbonization process (i.e. 600oC and 700oC) with the same duration, which is 2 hours. While, microscope imaging is being conducted to see the particles of all the samples, which are dried bamboo, bamboo-derived AC 1h, 600oC, bamboo-derived AC 1h, 700oC, bamboo- derived AC 6h, 600oC, and bamboo-derived AC 6h, 700oC up close. With this, the effect of milling can be observed. Not only that, but this study also investigated the effect of bamboo- derived AC on the dehydrogenation properties of complex metal hydride by adding 10% of AC into lithium aluminium hydride, LiAlH4. The objective is to evaluate its potential as a catalyst for improving hydrogen desorption kinetics. These findings contribute to the understanding of the role of mechanically ground bamboo-derived AC in material characterization and its potential as a catalyst for enhanced hydrogen release.
