SrTiO3 crystallites were successfully synthesized by the electrochemistry method ,and the effect of electric current on the crystallization ,morphology and photocatalytic property was mainly investigated by using XRD ,TEM , UV-Vis and technique of photo degradation of methyl orange solution ,respectively .SrTiO3 nanocrystallites with ball shape and diameter of 60 nm could be obtained at 3 A under room temperature and the onset of the absorption appears at about 380 nm . The photo catalytic efficiency of the as-prepared nanoparticles is 93% in 100 min . The designing experiment with simple route includes a lot of knowledge and is beneficial to develop students ’ ability on using knowledge and carrying out scientific research flexibly ,thus it can be applied as a comprehensive experiment of the experimental course of the students majored in material chemistry .
