Abstract
ZnO nano-rods were synthesised via wet chemical method at different nitrate concentration and pH value. The effect of pH and nitrate concentration on the size and morphology of the prepared ZnO photocatalysts have been investigated by particle size distribution analysis and Field emission scanning electron microscopy respectively. Additionally, UV-Visible spectroscopy and energy dispersive studies and were carried out to confirm the optical and compositional properties of the prepared ZnO powder. The estimated band gap of the as prepared ZnO photocatalysts at different pH and nitrate concentration calculated on the basis of Kubelka–Munk function was found to be in the range of ∼2.7–3.6 eV. Field emission scanning (FE-SEM) and transmission electron microscopic (TEM) observations reveal rod-like morphology. The photocatalytic activity of prepared ZnO photocatalysts was evaluated by photo degradation of the mixture of Methylene Blue (MB) and Rhodamine 6G (Rh 6G) solution under simulated solar radiation. Volume of hydrogen evolution was recorded in the presence of prepared ZnO photocatalysts in 2 h. Nitrate concentration, and pH value showed a significant effect on the optical and morphological behaviour of the prepared ZnO powdered photocatalysts.
