"The essence of presented result is the preparation of nanocomposites based on phyllosilicate montmorillonite with an anchored zinc oxide (ZnO) nanoparticles. While the photocatalytic properties of ZnO nanoparticles are not affected by anchoring on montmorillonite, the potential environmental risk from ZnO nanoparticles is suppressed because montmorillonite matrix prevents their release into the environment."@en . .
