Up to now, researches about biomass conversion have intensively investigated on carbon material fields owing to their specific characteristics such as abundance, ease of processing and eco-friendly. In this study, a kind of wooden biomass which is called as empty fruit bunch (EFB) from oil palm tree was investigated as a carbon precursor. Our strategy is to convert carbon substances concluding lignin, which is a main component of wooden biomass also the secondly plentiful aromatic biopolymer, to hierarchically nano-sized porous carbonaceous material with high surface area. Hydrothermal carbonization and chemical activation were conducted to change precursor to object porous carbonaceous material having ultrahigh specific surface area over 3000 m2 g-1. Based on their ultrahigh specific surface area and hierarchical pore structure, the product offers outstanding electron percolation properties. The excellent ion and electron transport abilities of as-obtained porous carbon are observed to be an advantage for high supercapacitive performances. |
