The mesoporous graphitic carbon nitride (mpg‐C3N4/r, r was defined as the initial
silica/dicyandiamide mass ratio) was successfully synthesized by heating the mixture of …

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

Adsorption of Cr (III), Mn (II), Cu (II) and Zn (II) on an oxidized activated carbon cloth was
studied. Its surface chemistry was characterized by potentiometric titration. This technique …

In this work, unburnt coal (UC) in bottom ash from coal-fired power plants was soaked in
KOH solution and activated for 1 h at 780° C. The yield of activated carbons varied from 47.8 …

The effects of functional groups on the adsorption efficiency of nitrate and nitrite from water
by carbon cloth were investigated. The carbon cloth was treated by sulfuric acid and used for …

Three activated carbons and two chars made from low rank coal were evaluated in terms of
their ability to remove the organic compound 4-nitrophenol (4-NP) and natural organic …

Ammonia adsorption was studied under dynamic conditions, at room temperature, on
activated carbons of different origins (coal-based, wood-based and coconut-shell-based …

The feasibility of preparing activated carbon (AC-CHs) from carbohydrates (glucose, sucrose
and starch) with phosphoric acid activation was evaluated by comparing its physicochemical …

Activated carbon (AC) is very effective for multi-pollutant removal; however, the complicated
components in flue gas can influence each other's adsorption. A series of adsorption …
