Adsorption by nanoporous media is critically involved in many fundamental geological and geochemical processes including chemical weathering, element migration and enrichment, environmental pollution, etc. Yet, the adsorption behavior of metal ions on nanoporous materials has not been systematically investigated. In this study, MCM-41 material with a monodisperse pore size (4.4 nm) and a large BET...
A series of SiO 2 and TiO 2 co-pillared montmorillonite photocatalysts with excellent adsorption capacity and high photocatalytic activity were synthesized via a sol–gel method by pillaring both SiO 2 and TiO 2 mixed sol into sodium montmorillonite. Various material characterization techniques such as powder X-ray diffraction (XRD), nitrogen adsorption/desorption isotherms...
