چكيده فارسي :
We developed a thermo-electrochemical method to grow copper-decorated TiO2 nanotubes (TiNTs) on a Ti-2wt.%Cu metastable alloy, prepared via rapid cooling heat treatment. Electrochemical anodization and UV illumination led to Cu-nanoparticle adorned TiNTs on the metastable alloy. Compared to non-annealed and pure Ti substrates, the metastable alloy exhibited superior TiNTs density and Cu-nanoparticle distribution. Characterization via SEM and XPS confirmed the Cu-decorated TiNTs structure. Notably, these Cu-TiNTs on the metastable alloy demonstrated a 7-fold and 4-fold increase in photocatalytic H2 generation compared to non-annealed and pure Ti substrates, respectively.
