Plasmonic Au/p-GaN Nanostructured Photocatalysts for Photoelectrochemical CO<sub>2</sub> Reduction
Photoelectrochemical (PEC) CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> reduction holds a significant route for converting solar energy into value-added fuels. p-type GaN is a novel class of semiconductor for hot hole collection from plasmonic Au to drive the PEC reaction. Here, we investigate the PEC performance of bare p-GaN photocathodes under 100 mW/cm<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> illumination. The photocathodes were fabricated using a scalable silica nanosphere patterning technique. The overall aim is to yield syngas (CO+H2) under unassisted condition combining plasmonic Au into nanostructured p-GaN photoelectrodes.
