Now-a-days there is shortage of pure water in several areas. So, the emerging technology solar driven desalination is one of the core practices that employ solar energy for fresh water making in sunny areas with lacking quality of water resources. In this work, the nano structure was developed using two step anodization procedure. Anodization was performed on pure aluminum foil (99.99 % purity) in 0.3 M of oxalic acid at constant voltage and effect of temperature on the morphology of formed porous anodic aluminum oxide (AAO) film was investigated. The temperature is varied between −5 to 25 °C. The characterization of the material is done using Scanning Electron Microscopy (SEM), Energy dispersive X-ray (EDAX), Ultraviolet-Differential reflectance spectroscopy (UVDRS). It is observed that, at −5 °C, micro indentations are formed on surface. At 5 °C, pores are randomly formed on the surface. At 15 °C, nano balls are formed on the surface. Whereas, at 25 °C, complete nano porous structure is formed. Hence, the formed nano structures were applied in solar driven desalination. In comparison to all other temperatures, we have observed that, the nano porous structure developed at 25 °C has 27 % of higher evaporation than the conventional.
