Abstract Scope |
Semiconductor nanostructures have advanced water waste photolysis and hydrogen production. Thin-layer ceramic materials are crucial for various applications, exhibiting distinct properties from bulk materials. This study investigates substrate influence on magnesium-grafted zinc oxide thin layers' properties. Samples were prepared on ceramic and glass substrates under identical conditions. XRD analysis revealed polycrystalline wurtzite structures with varying grain sizes. UV-visible absorbance showed Zr-doped ZnO films absorb visible light around 410 nm, with a blue shift as magnesium content increased. The band gap widened to 2.93 eV for ceramic substrates. SEM analysis demonstrated doping significantly affected ZnO morphology. Photocatalytic activities, assessed using orange II degradation, showed magnesium doping improved performance on ceramic substrates compared to glass. The photolysis mechanism revealed Zr-ZnO networks enhance hydroxyl ion adsorption, acting as trap sites to reduce hole/electron pair recombination, thus increasing photodegradation efficiency. This research contributes to developing advanced materials for photocatalytic applications. |
