Rice husk, a renewable agricultural by-product, was used as a precursor for the fabrication of high performance porous carbons for supercapacitors by ZnCl 2 activation with or without microwave-assisted heating. Microporous carbons with the surface area bigger than 1442m 2 /g are made at a ZnCl 2 /rice husk mass ratio as low as 1/1 from rice husk, which is really worthwhile...
Porous carbons (PCs) including microporous and mesoporous carbons for supercapacitors were made from rice husk through zinc chloride (ZnCl2) activation in one-step by microwave heating with microwave power at 600 W at 20 min heating time. PCs were characterized by field emission scanning electron microscope, transmission electron microscope and x-ray diffraction. The pore structure parameters and...
