Visible-light-driven photodegradation of organic pollutants by simply exfoliated kaolinite nanolayers with enhanced activity and recyclability.

The need for abundant photocatalyst in wastewater treatment is currently a must. A simple intercalation process was utilized to exfoliate Kaolinite clay mineral structure AlSiO(OH) into two-dimensional nanostructured separated layers operated in visible light range. The intercalating agents were hydrazine hydrate and urea.
