Synthesis, characterization and supercapacitive properties of hierarchical po…
Abstract. A series of hierarchical porous carbons are synthesized from metal-organic frameworks as a precursor and glycerol as a carbon source. N2 adsorption–desorption measurement indicates that glycerol has a pronounced effect on the specific surface area of the synthesized porous carbons. And the pore size distribution and BET can be modulated by adding different amounts of Bi(NO3)3·5…

Rice husk-derived porous carbons with high capacitance by ZnCl2 activation fo…
Abstract. Rice husk, a renewable agricultural by-product, was used as a precursor for the fabrication of high performance porous carbons for supercapacitors by ZnCl2 activation with or without microwave-assisted heating. Microporous carbons with the surface area bigger than 1442 m2/g are made at a ZnCl2/rice husk mass ratio as low as 1/1 from rice husk, which is really worthwhile from the v…

Abstract. Activated carbon aerogels (ACAs) with hierarchically porous structures and high specific surface area have been prepared via CO2 and KOH activation processes. The pore structures of ACAs are characterized by N2 adsorption/desorption and scanning electron microscopy. The experimental results show that the ACAs contain three types of pores: micropores with diameters below 2 nm, smal…

Porous carbon with tailored pore size for electric double layer capacitors ap…
Abstract. A series of porous carbon samples as electric double layer capacitor electrode materials were prepared by a pyrolysis process using phenol formaldehyde resin (PF) as precursors and KOH/ZnCl2 as activation agents. Porous carbon samples were characterized by thermogravimetric analysis, X ray diffraction, nitrogen adsorption/desorption isotherms and transmission electron microscopy. …

Nitrogen-doped porous carbon simply prepared by pyrolyzing a nitrogen-contain…
Abstract. Nitrogen-doped porous carbons are very simply prepared by direct pyrolysis of a nitrogen-containing organic salt, the tetrasodium salt of ethylenediamine tetraacetic acid for example, at 600–900 ◦C in an inert atmosphere without activation. The porosity and surface chemistry of the carbon depend strongly on the pyrolysis temperature. The surface area and pore volume increase w…

Macro–microporous carbon for supercapacitors derived from rape seed shell
Abstract. In this work, a novel macro–microporous architecture is successfully constructed in a honeycomb-like structure by directly using rape seed shell via impregation-activation route. This approach permits the high specific surface area (SSA) and a unique hierarchical porous structure which consists of interconnected macroporous skeleton and a significant microporosity. The unique ho…

High capacitance electrode materials based on layered double hydroxides prepa…
Abstract. Supercapacitors that have been actively sought for electricity storage and many metal oxides/hydroxides, including transition metal-containing layered double hydroxides (LDHs), have been widely investigated. In this research, Co- or Mn-containing LDHs were prepared through precipitation in methanol, followed by the hydrothermal treatment and dispersion in water. As-prepared LDHs show…

Hierarchical porous carbon microspheres derived from porous starch for use in…
Abstract. Porous starch was used as a precursor for hierarchical porous carbon microspheres. The preparation consisted of stabilisation, carbonisation and KOH activation, and the resultant hierarchical porous carbon microspheres had a large BET surface area of 3251 m2 g-1. Due to the large surface area and the hierarchical pore structure, electrodes made of the hierarchical porous carbon m…

Abstract. Carbon nanofibers (CNFs) containing boron and nitrogen are prepared from polyacrylonitrile and boron trioxide (B2O3) by using simple electrospinning. The B2O3 introduction into a PAN solution causes a porous structure with stabilized [O]BN functional groups to develop in the processes of stabilization and carbonization. The pore structure and the functional groups such as B atoms …

Abstract. High specific surface carbon (Black Pearls 2000) has been modified by electroactive anthraquinone (AQ) groups by spontaneous reduction of the corresponding in situ generated diazonium derivative. A set of modified carbons with different AQ loadings have been synthesized to study the effect of the grafted groups on the pore texture and on the double layer capacitance of the modifi…

Abstract. N-doped carbon replicas of zeolite Y are prepared, and the effect of cation nature of zeolite (H+ or Na+) on the carbon replicas is studied. The morphology, structure and surface properties of the carbon materials are investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), N2 adsorption, X-ray photoelectron spectroscopy …
