17. The Correlation between Structural and Optical Properties of Zinc Hydroxide Nanoparticle in Supports Photocatalytic Performance
Zn(OH)₂ nanocrystals were green-synthesized using Coleus blumei Benth leaf extract by varying the pH and calcination temperature. FTIR, UV–Vis, and XRD analyses were employed to investigate their structural, optical, dielectric, phonon vibration, and photocatalytic properties. Increasing the calcination temperature enhanced the LO–TO phonon separation, plasma frequency, bandgap, and stable covalent bonding within the lattice. The optimum condition of 600 °C and pH 7 exhibited the fastest photocatalytic degradation performance, demonstrating the strong correlation between the structural and optical properties of Zn(OH)₂ and its photocatalytic activity.
