Abstract

In this research, new morphological nanostructures (Ns) prepared using a simple electrochemical anodization is described. The electrochemical process was carried out on Sn foils at a constant potential of 5 V for 10 min. To study the surface morphology effect on the photoactivity, the electrolyte concentration was chosen as the key factor using 1 mM and 5 mM. X-ray diffraction (XRD) disclosed tetragonal crystalline of . Also, the surface morphologies imaged by a field-emission scanning electron microscope (FE-SEM) showed nanorocks and nanoparticles instead of traditional porous. Furthermore, fluorescence measurements revealed that the energy gap of was 3.76 eV. The photocatalytic efficiency for the discoloration of methylene blue (MB) dye was found to be 94 % after 140 min of solar irradiation. The results confirmed the connection of photoactivity with the electrolyte concentration and suggest the ability to fabricate high photocatalyst nanostructures preparation using this technique.
