This article covers little specific outcomes and connotations related to the photocatalytic properties of titanium oxide films distinctively doped by platinum, and deposited on a silicon substrate by means of the PLD technique. Through I-V spectroscopic investigates, laser-beam-induced current (LBIC), optical reflectivity and impedance spectroscopy, it is followed that an ideal percentage somewhere in the range of 0.2% and 0.3% of Pt invites updating an extremely fascinating photocatalytic execution of such structures against methylene blue photodegradation (MB) as a dye in the UV-visible spectral tape.
