Rapid synthesis of hexagonal-shaped Zn(Al)O-MMO nanorods for dye-sensitized solar cell using Zn/Al-LDH as precursor

This study reports a simple new technique for the preparation of novel hexagonal-shaped mixed metal oxides (MMO) nanorods using Zn/Al-layered double hydroxide (LDH) as a precursor for dye-sensitized solar cell (DSSC) application. The effect of the Zn to Al molar ratio demonstrated a sound correlatio...
