Symbiotic Interaction of Amalgamated Photocatalysts with Improved Day Light Utilisation and Charge Separation

<jats:title>Abstract</jats:title><jats:p>A promising amalgamation of organic with inorganic semiconductor photocatalyst (g‐C<jats:sub>3</jats:sub>N<jats:sub>4</jats:sub>/SrTiO<jats:sub>3</jats:sub>) with varied g‐C<jats:sub>3</jats:sub>N<jats:sub>4</jats:sub> concentration was synthesised through a simple thermal method. The organic semiconductor was prepared through a facile pyrolysis of urea while perovskite (SrTiO<jats:sub>3</jats:sub>) by sol‐gel hydrothermal route. The observed mechanistic characteristics of the synthesised composite photocatalysts were thoroughly analysed through robust analytical tools. The dissection analysis clearly revealed that amalgamation of organic semiconductor stimulated the utilisation of solar spectrum by enhancing the light absorption towards visible band. Where else perovskite activated close interfacial connections leading to enhanced efficiency of electron migration. The Electron Paramagnetic Resonance (EPR) excited under solar spectrum along with Photoluminescence (PL) clearly indicated the prolongation of the charge carriers. A symbiotic interaction with mutual benefit was clearly observed between these photocatalysts. The solar photocatalysis ability of the perovskite composite was examined by degrading a non‐photosensitising compound (Bisphenol A). The photocatalysis experiment clearly revealed its dominant solar light harvesting capability of the developed perovskite amalgamated organic photocatalyst.</jats:p>
