Metal Doped

Ce, Nd and Gd doped strontium titanate nanomaterial was prepared by a sol-gel method. Effects of transition metals doping on photocatalytic activities of the prepared materials were studied. The pure strontium titanate had photocatalytic degradation activity of 31.0%. The maximum degradation rate happened at Ce content of 20% and nearly 32.5% of the initial methyl orange was degraded on the material after 30 min of irradiation. Although there was a slight variation of photocatalytic degradation rate with the increasing Nd doping content, the materials doped with Nd had lower photocatalytic activity compared with pure strontium titanate. Nearly all the samples doped with Gd in the range up to 30% had much lower activity that the pure strontium titanate.
