Abstract
High surface area activated carbon fibers (ACF) have been prepared from bamboo by steam activation after liquefaction and curing. The influences of activation temperature on the microstructure, surface area and porosity were investigated. The results showed that ACF from bamboo at 850 °C have the maximum iodine and methylene blue adsorption values. Aside from the graphitic carbon, phenolic and carbonyl groups were the predominant functions on the surface of activated carbon fiber from bamboo. The prepared ACF from bamboo were found to be mainly type I of isotherm, but the mesoporosity presented an increasing trend after 700 °C. The surface area and micropore volume of samples, which were determined by application of the Brunauer-Emmett-Teller (BET) and t-plot methods, were as high as 2024 m2/g and 0.569 cm3/g, respectively. It was also found that the higher activation temperature produced the more ordered microcrystalline structure of ACF from bamboo.

In recent years, growing research interest has been focused on various natural materials, which can be used for the production of ACFs with high adsorption capacity
From these figures it is clear that the rough surfaces of BACFs can be detected as knots and bubbles
Summary
Activated carbon fibers (ACFs) are relatively novel fibrous adsorbents that show important advantages with respect to conventional activated carbons due to the handled and the faster. Most ACFs have been synthesized from precursors based on the fossil fuels The shortage of these resources necessitates an improvement in ACFs production which highly depends on chemicals [2,3,4]. Limited reports were found using bamboo as raw materials for the preparation of high surface ACFs, except activated carbon [11,12,13,14]. Liquefaction technique can completely convert wood or bamboo into useful liquid chemical raw [16,17,18], which greatly improves the utilization of these materials, and provides a new method for the preparation of bamboo based ACFs. some studies have reported the preparation of carbon fibers from liquefied wood instead of fossil fuels [19,20]. The adsorption performance of BACFs, the iodine and methylene blue (MB) adsorption of BACFs under different activation temperatures were studied
