Designing TiO₂ Nanotubular Arrays with Au-CoO_x Core-Shell Nanoparticles for Enhanced Photoelectrochemical Methanol and Lignin Oxidation.

ABSTRACT: One-dimensional (1D) ordered TiO₂ nanotubes exhibit exceptional charge transfer capabilities, making them suitable candidates for constructing visible-light-active photoanodes in selective PEC oxidation reactions. Herein, we employed a facile and easily scalable electrochemical method to fabricate Au-CoO_x-deposited ordered TiO₂ nanotubular array photoanodes. The improved visible light absorption capacity of TiO₂-Au-CoO_x, with unhampered 1D channels and the controlled integration of Au between TiO₂ and CoO_x, along with their synergistic interaction, have been identified as the most promising strategy for enhanced PEC performance, as evidenced by an IPCE of 3.7% at 450 nm. Furthermore, the robus
