Mesopore-dominant porous carbon derived from bio-tars as an electrode material for high-performance supercapacitors

open access: yesJournal of Saudi Chemical Society, 2019
For the first time, toxic bio-tars collected from the gasification of pine sawdust are used as the precursor for activated carbons. Various types of activation agents including KOH, K2CO3, H3PO4 and ZnCl2 were screened for obtaining superior activated ...

Preparation of controlled porosity carbon aerogels for energy storage in rechargeable lithium oxygen batteries [PDF]

open access: yes, 2009
Porous carbon aerogels are prepared by polycondensation of resorcinol and formaldehyde catalyzed by sodium carbonate followed by carbonization of the resultant aerogels in an inert atmosphere. Pore structure of carbon aerogels is adjusted by changing the
