Au nanoparticle (NP) sensitized ZnO nanopencil arrays were synthesized on FTO substrates by aqueous chemical growth followed by photoreduction, yielding a photocurrent of [similar]1.5 mA cm-2 at 1 V vs. Ag/AgCl. The enhanced photocurrent is attributed to the surface plasmon resonance effect of Au NPs and a prolonged photo-generated electron-hole pair lifetime.
