Titanium Carbide Derived Nanoporous Carbon for Energy-Related Applications
Ranjan Dash,John Chmiola,Gleb Yushin,Yury Gogotsi,Giovanna Laudisio,Jonathan P. Singer,John E. Fischer,Sergei O. Kucheyev +7 more
TL;DR: In this paper, high surface area nanoporous carbon has been prepared by thermo-chemical etching of titanium carbide TiC in chlorine in the temperature range 200-1200-C. Structural analysis showed that this carbide-derived carbon was highly disordered at all synthesis temperatures.
Journal ArticleDOI
Tailoring of nanoscale porosity in carbide-derived carbons for hydrogen storage.
TL;DR: It is shown that carbon materials can be rationally designed for H2 storage, and gravimetric hydrogen storage capacity normalized to total pore volume is optimized in materials with primarily micropores rather than mesopores, in agreement with theoretical predictions.
Journal ArticleDOI
Importance of pore size in high-pressure hydrogen storage by porous carbons
Yury Gogotsi,Cristelle Portet,Sebastian Osswald,Jason M. Simmons,Taner Yildirim,Giovanna Laudisio,John E. Fischer +6 more
TL;DR: In this article, the pore size and shape of carbide-derived carbons (CDCs) has been investigated for hydrogen storage at high pressure and low temperature and it has been experimentally demonstrated that pores of 0.6-0.7 nm in diameter provide the largest H 2 uptake per unit SSA at elevated pressures and liquid nitrogen temperatures.
Journal ArticleDOI
Carbide-derived carbons: a comparative study of porosity based on small-angle scattering and adsorption isotherms.
TL;DR: This work applies a second indirect method, small-angle X-ray scattering (SAXS), to study porosity in carbide-derived carbons (CDC), and results qualitatively confirm and reinforce model-dependent conclusions drawn from gas sorption isotherms.
Carbide-derived carbons designed for efficient hydrogen storage
TL;DR: In this article, the fundamental relation between capacity and specific surface area (SSA), pore size and pore volume is established for CDC-based hydrogen storage, and the pore-size distribution by carbide precursor selection and etching temperature yields enhanced hydrogen storage capacity at ambient and elevated pressure.
