  Titanium based-perovskites have got surprising attraction due to their
environmentfriendly 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.
