Light-driven nanomotors have gained significant attention due to their ability to perform reversible and repetitive motion behaviors with immediate photoresponse. Photocatalytic nanomotors, based on photocatalysts, are a notable category that may use energy from external light sources and surrounding chemicals for efficient propulsion [1]. These nanomotors can convert optical and chemical energy inputs into mechanical motion via photocatalytic reactions, allowing propulsion modification based on parameters like chemical concentration or light intensity. In this work, a novel advanced TiO/Zn/zeolite nanomotor with high photocatalytic and optical characteristics is proposed to enhance dye degradation and to enable real-time optical detection under UV light [2, 3]. This composite that is synthesized by hydrolysis deposition and calcination integrates the photocatalytic efficiency of TiO2, the improved UV absorption properties of Zn, and the elevated surface area and porosity of zeolite. These synergistic properties empower the effective production of reactive oxygen species (ROS) under UV light, resulting in the breakdown of methyl blue dye with over 97% efficiency at pH 12. The schematic representation in Figure 1 illustrates the preparation process, photodegradation performance, characterization, and potential applications of TiO/Zn/zeolite nanoparticles, highlighting their effectiveness in methyl blue degradation under UV light and their suitability for sensor applications. The use of Zn significantly decreases the bandgap of TiO2, enhancing light absorption and charge separation, while the zeolite as a template guarantees uniform dispersion of metal nanoparticles, avoiding agglomeration and offering supplementary active sites because of the mesoporous structure of the zeolite [4]. The material's remarkable optical properties, resulting from its ability to absorb UV light and generate quantifiable optical signal changes during photocatalytic processes, allow its incorporation into optical sensors for the real-time monitoring of residual dye concentrations. This multifunctional nanomotor offers a rapid, economical, and reliable solution for industrial wastewater treatment, exhibiting significant potential for environmental remediation applications.
