Hierarchically porous carbon derived from wheat straw
Porous biochar for anode material of lithium ion battery (LIBs) was prepared from wheat straw, one of the most common biomass of agricultural waste in China, with KOH using as activator. Microstructure of the porous biochar was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) as well as Brunauer–Emmett–Teller (BET). The porous biochar prepared contains parallel

One
Hierarchically porous carbon (HPC) material based on environmental friendliness biomass has spurred much attention, due to its high surface area and porous structure. Herein, three-dimensional (3D) N,O co-doped HPC (N–O-HPC) was prepared by using a one-step fabrication process of simultaneously carbonizing and activating soybean dregs and used as an electrode for supercapacitors (SCs).
Evaluating biomass
As a promising renewable resource, biomass has several advantages such as wide availability, low cost, and versatility. In this study, we use peanut shell, wheat straw, rice straw, corn stalk, cotton stalk, and soybean stalk as the precursors to synthesize hierarchically porous carbon as the positive electrode material for hybrid Na-ion capacitors, aiming to establish a criterion of choosing

Research on High
2021/3/31Biomass-derived porous carbon can inherit special microstructures from precursors, which provide active sites for many ions transport channels and energy storage. High specific surface area and hierarchical porous structure are the most important two main factors, which would affect the electrochemical properties of carbon materials [ 11 ].
Nitrogen
In this paper, wheat straw was converted into nitrogen-doped hierarchical porous carbon (N-HC) by direct pyrolysis of wheat straw with CaCl2 as an activator and melamine as a nitrogen resource. The as-prepared samples exhibit different hierarchical porous structures and nitrogen contents in a temperature range from 600 to 800 C. Compared with other samples, the N-HC-800 displays a large
