摘要：
Zn(NO3)(2)center dot 6H(2)O and C4K2O9Ti center dot 2H(2)O with 1:1 and 2:1 M ratios of Zn:Ti in solutions at the pH 10 were irradiated by 180 W microwave radiation for 40 mm to form ZnO/TiO2 nanocomposites, new candidates for photodegradation and photoreduction in UV light with very high efficiency. Upon processing the nanocomposites at high temperatures, pure Zn2TiO4 nanocrystals were synthesized only by the 700 degrees C and 3 h calcination of the 2:1 M ratio Zn:Ti precursors.
