  "abstract": "Advancing efficient hydrogen production requires new electrocatalysts with tenable activity and stability. Here, titanium dioxide nanotubes (TNTs) are engineered via atomic layer deposition (ALD) of palladium (Pd) and tin oxide (SnO₂) to unlock synergistic effects for hydrogen evolution reaction (HER) enhancement. The study highlights how controlled deposition of Pd and SnO₂ influences the nanotubes morphology, structure, and electrochemical properties. The Pd/SnO₂ co-modified TNTs showed synergistic enhancement for HER, achieving overpotential of approximately 160 mV at a current density of 10 mAcm⁻² and a low Tafel slope of about 52 mVdec⁻¹ for the best-performing sample and excellent stability over 48 h at 10 mAcm⁻². Impedance spectroscopy confirms superior charge transfer in these heterostructures compared to bare TNTs and singly modified electrodes. Moreover, the Faradaic efficiency calculated for the best-performing sample is 98 ± 2 %, while H₂ production rate equals 183 ± 2 μmolh⁻¹cm².",
