Titanium based-perovskites have got surprising attraction due to their environment-friendly photocatalysts behavior. The Rietveld refinement of X-ray diffraction (XRD) pattern authenticates the orthorhombic Pnma structure of Pr₂MgTiO₆ (PMT). The Pr³⁺-Ti⁴⁺ intervalence charge transfer process plays an important role inside PMT. The dc conductivity shows a change in the hopping mechanism from nearest-neighbor hopping to a variable range hopping due to the activation energy reduction. This change in the hopping mechanism is well supported by both the relaxation time and impedance data in PMT. The constant phase element (CPE) model is utilized to fit impedance plots. The photocatalytic activity of PMT was performed under UV irradiation with the help of degradation kinetics of organic pollutants. Also, the photocatalytic efficiency of recycled and reused PMT finds 91.2% after 5th cyclic runs. The calculated band-gap is found to be 3.58 eV.

钛基钙钛矿由于其环境友好的光催化剂行为而获得了惊人的吸引力。X 射线衍射 (XRD) 图案的 Rietveld 细化验证了Pr ₂ MgTiO ₆ (PMT)的正交Pnma结构。Pr ³⁺ -Ti ⁴⁺间隔电荷转移过程在 PMT 中起着重要作用。由于活化能降低，直流电导率显示了从最近邻跳跃到可变范围跳跃的跳跃机制的变化。PMT 中的弛豫时间和阻抗数据很好地支持了跳跃机制的这种变化。恒定相位元件 (CPE) 模型用于拟合阻抗图。借助有机污染物的降解动力学，PMT 的光催化活性在紫外线照射下进行。此外，在第 5 次循环运行后，回收和再利用的 PMT 的光催化效率为 91.2%。计算出的带隙为 3.58 eV。
