In this research, we have prepared a new type of multistage aperture nitrogen-doped carbon
materials [CN-x,(x= 600, 700, 800, 900, 1000)] by one-step carbonization at different …

The influence of surface modification of activated carbon with gaseous ammonia on
adsorption properties toward carbon dioxide (CO2) was reviewed. It was apparent from the …

Activated carbon (AC), after successive adsorption–regeneration processes, is found to lose
its capacity in the adsorptive removal of nitrogen (N) and sulfur (S) containing compounds …

Mesoporous carbons are widely utilized as adsorbents for adsorptive removal of nitrogen-
containing compounds in fuel. Herein, hollow mesoporous carbon nanospheres (HMCNs) …

Nitrogen-doped porous carbons (N-RFCC) were prepared by NH3N2 mixture gas treatment
at high temperature during the carbonization process on resorcinol–formaldehyde cryogels …

Microalgae bio-oil is of interest as a potential alternative to traditional fossil-fuel-based
transportation fuels. However, the presence of nitrogenous compounds in the bio-oil can …

Quaternary nitrogen (NQ) functionalized porous carbon could be prepared from thermally
stabilized polyacrylonitrile (PAN) fiber (PYR) by ZnCl 2 activation (PYR-7Z4) and …

The study of CO2 adsorption on adsorbent materials is a current topic of research interest.
Although in real operating circumstances, the removal conditions of this gas is carried out at …

A commercial granular activated carbon (GAC) was subjected to thermal treatment with
ammonia for obtaining an efficient carbon dioxide (CO2) adsorbent. In general, CO2 …

Abstract The perchloroethylene (PCE, tetrachloroethylene), as a representative of
chlorinated ethylenes and volatile organic compounds (VOCs), can be easily transported …
