Adsorption

Microporous oxide materials are widely used in various areas of chemical and petrochemical industry as supports of catalytically active components as well as catalysts for other acid-catalyzed reactions. Such microporous materials play an …

The adsorption of cesium on mesoporous silica materials containing embedded phosphotungstic acid (PTA) was studied. The materials contained active adsorbent and binders: γ-Al2O3, kaolin, or charcoal. The presence of Keggin units of PTA in the …

The adsorption process at near ambient temperatures indicated that the EEC (enthalpy–entropy compensation) is affected by three basic thermodynamic values: ∆H, ∆S and T. The consequence is that it is possible to determine an isosteric straight …

First-principle calculation reveals that N containing carbon nanotubes (CNTs) can support the functionalization of transition metals such as Sc on the CNT surface. For N-substituted CNTs without a vacancy, the enhanced adsorption results from …

To enhance the gas adsorption of toxic industrial chemicals such as NH $$_3$$ 3 and SO $$_2$$ 2 , a biphasic carbon silica composite (CSC) is functionalized with combinations of potassium carbonate or potassium phosphate and various metal …
