This study describes the direct deposition of extremely dense TiO2 nanorods (NRs) on an ITO substrate for improved detection heavy metal ions (HMIs). A facile hydrothermal method was employed to synthesize NRs at ~130 °C. Synthesized were analyzed morphological, structural, and electrochemical properties. As electrode material, used simultaneous three HMIs (i.e., Cr3+, Cu2+, Hg2+), which showed a remarkably high sensitivity ~92.2 µA.mM−1.cm−2 Cu2+ ion. Relatively low sensitivities ~15.6 ~19.67 recorded Cr3+ Hg2+ ions, respectively. The fabricated NR-based HMI sensor effective dynamic linear range with LOD values ~21.7 mM, 37 ~ 28.5 mM Hg2+, exhibited efficient charge transfer over toward trace Hg2+. Moreover, reliability assessed, promising stability 30 days. obtained results indicate that grown are material detecting hazardous might eventually be commercialized in near future.
