Serb. Chem. Soc. VL - 87 IS - 9 SE - Physical Chemistry DO - 10.2298/JSC211203058B UR - https://shd-pub.org.rs/index.php/JSCS/article/view/11868 SP - 1035-1048 AB - <p>The preparation and properties of oxide coatings with immobilized ZSM-5 zeolite obtained by plasma electrolytic oxidation on aluminum support were investigated and discussed. Pure and Ce-exchanged ZSM-5 were immo­bilized on aluminum supports from a silicate-based electrolyte under ultra-low duty cycle pulsed direct current conditions. The obtained composite coatings were characterized with respect to their morphology, phase and chemical com­position, as well as photocatalytic activity and anti-corrosion properties. All mentioned properties of the obtained coatings were dependent on the proces­sing time. The coatings with Ce-exchanged ZSM-5 showed higher photocat­alytic activity and more effective corrosion protection than those with pure ZSM-5. The highest photocatalytic activity was observed for coatings pro­cessed for 30 min. It is suggested that the surface morphology, Ce-content and number of defects influenced the photocatalytic activity of the composite coat­ings.</p> ER -
