In this paper, spinel-type aluminate photocatalysts MAl2O4 （M= Cu, Zn） were synthesized by organic precursor method. These samples were characterized by XRD, TEM, etc. It is found that ZnAl2O4 powders were synthesized at 700℃ and CuAl2O4 with little CuO at 800 ℃. The results show that the decolorizing efficiency of methyl orange can reach 89. 4% by using ZnAl2O4 powders synthesized at 700℃ and 96.7% by using CuA1204 powders synthesized at 800 ℃ under 2 hours illumination of 100W mercury lamp.
