Titania@ITO‐Grown Nanoflakes: A Promising Heterocatalyst for 4‐Nitrophenol Reduction and Synergetic Profile Against Bacterial Growth

ABSTRACT The proposed study was undertaken to design a facile, straightforward recoverable Titania@ITO‐grown nanocatalyst, owning ironic catalytic sites synthesized via a liquid phase deposition protocol. The size, shape, charge, and morphological characteristics of the synthesized functional nanocatalyst were determined via zeta seizer, XRD, zeta potential, and SEM, critically disclosing ⁓5–6 nm, anatase crystalline nature, −44.0 mV, and flakes or sheet‐like morphology, respectively. The reuse of the nanocatalyst particles was evaluated for their catalytic and antimicrobial efficiency. The obtained data revealed that the titania nanocatalyst is promising for ultrafast reduction of organic pollutants (4‐nitrophenol) with 99% reduction efficiency, utilizing only 120 μg within 60 s following microwave‐assisted protocols. Moreover, phenomenal antibacterial activity was disclosed by the titania nanocatalyst against both gram‐positive and gram‐negative bacteria. The anticipated nanocatalyst is advantageous due to its ultrafine and economical design, a significant amount of reduction capabilities in a short space of time, along with extreme recyclability, with a negligible loss in reduction abilities. The nanocatalyst provided here is more valuable and useful than the disclosed methods, symbolizing an exceptional commercial icon.
