CO2 adsorption capacity of a commercial activated carbon was improved by using HNO3
oxidation, air oxidation, alkali impregnation and heat treatment under helium gas …

The effect of surface chemistry (nature and amount of oxygen groups) in the removal of
ammonia was studied using a modified resin-based activated carbon. NH3 breakthrough …

In order to understand the adsorption mechanism for removing heterocyclic sulfur/nitrogen
compounds from liquid hydrocarbons on activated carbon, the liquid-phase adsorption of …

Abstract Metal-organic framework (MOF)-derived carbons (MDCs) with remarkable porosity
were synthesized through pyrolysis of a MOF (metal-azolate framework-6 or MAF-6) in the …

The influence of surface acidity of activated carbon (AC) was experimentally studied on
adsorption of ammonia (NH3). Coconut shell-based AC was modified by various acids at …

Adsorption properties of activated carbons prepared from waste newspaper by chemical and
physical activation were investigated using water vapor, ammonia, methane, and methylene …

Air pollution related to the release of industrial toxic gases, represents one of the main
concerns of our modern world owing to its detrimental effect on the environment. To tackle …

In this work, the effects of different surface functional groups on the ammonia adsorption of
porous carbons modified by electrochemical treatment in acidic solution (HNO3) under …

Recently, the catastrophe of global warming by virtue of carbon dioxide emissions has
turned into paramount anxiety. To overcome this issue, various carbon dioxide capture and …

Activated carbon (AC) materials has been widely used to prevent acetone pollution. In such
process, the modification of AC is an effective way to improve the adsorption capacity of …
