Ultra-microporous carbons were prepared from CF (cellulose fibers) by physical activation at various temperatures. Physical activation using steam was observed to have an influence on the development of new pores and the expansion of pore sizes and to be effective in developing optimal micropores for CO2 adsorption on the carbon surface. On optimizing the preparation conditions, the synthesized materials...
Chemically A-MWCNT (activated multiwalled carbon nanotube)/PANI (polyaniline) composites produced via ultrasonic polymerization of an aniline monomer in the presence of A-MWCNTs were investigated as potential electrode materials for supercapacitors. These composites were compared to pristine MWCNTs and MWCNT/PANI composites. The influence of the pore structure, which developed because of the polymerization...
In this report, we describe the preparation of OMC (ordered mesoporous carbon) via a conventional templating method using mesoporous silica (SBA-15) as a Pt–Ru catalyst support for use in fuel cells. The influence of surface treatment of the carbon supports on the electrochemical properties of Pt–Ru/OMC was investigated by exposing the surface to hydrogen peroxide at concentrations of 0, 15, 30, 40,...
