Description
Summary:ZnO/Ag2O heterostructures, as the functional materials for photodegradation of MB dye under visible light irradiation, have been grown using inexpensive hydrothermal and ultrasonic-assisted synthetic routes. The heterostructures have revealed wurtzite ZnO peaks that demonstrate its highly crystalline and hexagonal structure, as well as the cubic Ag2O peaks. The ZnO/Ag2O photocatalyst has demonstrated two-step dye degradation slopes, with the higher-slope arising later in the process when the metallic-Ag traps the valence electrons of Ag2O nanoparticles and advances e–/h+ separation across the ZnO/Ag0/Ag2O heterojunction structures, making them readily accessible for superior dye degradation.
