Preparation of Mesoporous Biomass Carbon Derived from Corn Stalks and Formation Mechanism

Abstract

Different formational process could lead to diverse morphologies and properties. Therefore, the study on formation mechanism was very important to figure out the influence of formational process. The corn stalk core (CSC), as a kind of renewable biological resource, could be used as raw materials to prepare activated carbon materials (ACs) via carbonizing and activating. The transformational mechanisms on the every step and the variation of various components in the CSC were studied, which was supposed the feasible methods to enhance the performance. In addition, the process of cellulose trans-forming into the carbon and the carbon structure were deduced. The carbon materials prepared were characterized through a series of equipments, such as scanning electron microscopy (SEM) and nitrogen adsorption-desorption measurements (BET), the obtained results showed that the ACs with more pores and higher specific surface area than the materials unactivated. In the end, the ACs was applied as anode in the lithium ion batteries (LIBs) to test their electrochemical performances. Comparing the carbon materials unactivated, the role of activated process was revealed.

Mesoporous biochar derived from bamboo waste: Template/hydrothermal preparation and highly efficient pharmaceutical adsorption

“…Vast pore structures could be obtained by removing the templates from the final products. Moreover, some of these BET surface area and pore volume values were higher than those of some reported biomass derived mesoporous carbons such as corn stalks derived mesoporous carbon with a 737 m 2 /g surface area (Yu et al 2017) produced via pyrolysis and activation. β-Cyclodextrin-derived mesoporous carbons with the highest BET surface area and pore volume of 860 and 0.46 cm 3 /g, respectively (Xin et al 2017) and hydroxymethyl furfural derived mesoporous carbon with a specific surface area of 451 m 2 /g and pore volume of 0.36 cm 3 /g (Wang et al 2016) from hydrothermal method have been reported.…”

“…Some representative cases are summarized in Table . Utilizing corn, corn byproducts, and corn industrial products to produce nanostructured carbonaceous materials as anodes has been proposed as well. ,,− Some representative cases are summarized in Table . In this section, two representative cases are reviewed in detail.…”
