Abstract: Star shaped nano ZrO2 was synthesized by hydrothermal method without template and surfactant with Zr (NO3) 4 · 5H2O as zirconium source. The structure of ZrO2 powder was studied by many advanced analytical methods. The results show that CH3COO − the third − has a great influence on the formation of star ZrO2 nanostructures. The reason why the prepared ZrO2 has excellent catalytic activity was analyzed by UV-Vis diffuse reflectance spectroscopy. The effect of raw material ratio on the photocatalytic performance of ZrO2 was studied. The synthesized ZrO2 has a narrow band gap (3.50-3.85)
