Green hydrogen, proposed as a sustainable alternative for conventional fuels, has gained
utmost importance due to its reduced carbon footprint and potential application in …

It is estimated that all fossil fuels will be depleted by 2060 if we continue to use them at the
present rate. Therefore, there is an unmet need for an alternative source of energy with high …

Coal gasification fine slag (GFS) produced from industrial entrained-flow gasification plants
typically contains a large amount of residual carbon. Using the GFS coal flotation residue as …

Three Machine learning (ML) models were constructed and tested to model the hydrogen
adsorption of activated carbons (ACs). Although many efforts have been accomplished, the …

In this study, the adsorption capacity of activated carbon was enhanced after zinc chloride
activation. The effects of pore filling, n-π and π-π interaction and electrostatic interaction on …

Porous carbons provide a low-cost route to a highly stable material for the adsorption of
various gases. In particular, activated carbons (ACs) and zeolite templated carbons (ZTCs) …

Nitrogen-doped activated carbons (NACs) were produced from Brazil nut shells (BNS) using
a concurrent procedure of KOH-activation and N-doping using melamine (MM) …

Activated carbon (AC) was successfully synthesized through flotation deashing combined
with ZnCl 2 activation using coal slime (CS) as the raw material. The results showed that …

Crop residue management in India has been problematic for decades due to the in-situ
burning of crop residues causing climate change, health issues, and soil degradation. The …

A significant amount of coal fly ash is generated and this type of waste material causes
severe environmental hazards. Metal (Al and Fe) extraction from coal fly ash is beneficial to …
