• comparison obtained regarding the percentage of removal from adsorption and heterogeneous photocatalysis tests. The photocatalysis mechanism can be explained as follows: a semiconductor such as the BEPh and BEOx samples absorbs a photon, promoting an electron from the valence band (VB) to the conduction band

• natural clay has predominantly the bentonite phase (at least 50%), known as montmorillonite. Isomorphic substitution of cations between the interlayer space of montmorillonites by exchanging Na+, Ca2+, Mg2+, and Cu2+ cations add other functionalities to the resulting material [7]. Heterogeneous

• photocatalysis is a cost-effective alternative to biological treatment methods for purifying polluted water [8]. Using semiconductors as heterogeneous catalysts proves to be more efficient than traditional methods, as the photocatalytic process gradually decomposes contaminating molecules without generating
