Introduction: This research delves into the comprehensive characterization and comparative analysis of platinum (Pt)-doped titanium dioxide (TiO2) and TiO2 nanoparticle thin films by focusing on their potential for sensor applications. Method: This research encompasses a thorough exploration of the structural, morphological, optical, and sensing properties of these thin films and evaluates their suitability and performance in various sensing scenarios. Results: It discusses the synthesis methodology, characterization techniques employed, and experimental setups for gas sensing evaluations and presents detailed results and discussions highlighting the key findings regarding the sensor capabilities of Pt-doped TiO2 and TiO2 nanoparticle thin films. Conclusion: Powder X-ray diffraction (XRD) analysis of the prepared samples confirms the formation of a crystalline structure. This method is low-cost, extremely simple, and effective for producing TiO2 nanomaterials on a large scale.
