Abstract
A very simple approach with yeast cells as a biotemplate was proposed to synthesize a mesoporous hybrid Fe 2O 3 photocatalyst. The mesoporous structure of the resultant samples was characterized by BET, N 2 adsorption–desorption isotherms (NADI) and transmission electron microscopy (TEM). The chemical bond linkages in hybrid Fe 2O 3 samples were confirmed by Fourier transform infrared spectroscopy (FT–IR). The catalytic activities of mesoporous hybrid Fe 2O 3 on degradation of methyl orange were investigated under UV-light irradiation. The hybrid Fe 2O 3 (yeast cell amount is 0.6 g) samples dried at 80 °C and calcined at 300 °C exhibit high surface area and photocatalytic activity.
