Abstract
This study explores a novel photoelectrode composed of copper oxide (CuO), polyaniline (PANI), and gold (Au) for efficient hydrogen production through photoelectrochemical (PEC) water splitting. Structural and morphological analyses using various techniques confirm the successful fabrication of the ternary Au/PANI/CuO photoelectrode. The integration of Au, PANI, and CuO nanomaterials enhances light harvesting, facilitates charge transfer, and reduces charge recombination due to the plasmonic effect of Au and the synergistic interaction between PANI and CuO. The Au/PANI/CuO photoelectrode achieves a 300-fold increase in photocurrent density (15 mA cm-2 at -0.39 V vs. RHE) compared to pure CuO. Additionally, it demonstrates superior operational stability for 5 hours and records an IPCE of 45% at 500 nm. These findings pave the way for the development of high-performance and durable plasmonic/polymer/semiconductor photoelectrodes for sustainable and clean hydrogen generation.

Abstract
We prepared ZnO nanocomposites with WO3 or CuO nanostructures to improve the photocatalytic performance of ZnO nanostructures. Characterization of the nanocomposites using scanning electron microscopy, x-ray diffraction, UV-vis spectrometry and photoluminescence revealed the morphologies and wide light absorption range of the materials. The highest current densities of WO3/ZnO and CuO/ZnO nanocomposites were 1.28 mA cm-2 and 2.49 mA cm-2 at 1.23 V (versus a reversible hydrogen electrode) under AM 1.5 100 mW cm-2, which are ~1.2- and 3.5-fold greater than those of bare ZnO nanostructures, respectively. The easy fabrication process suggests that nanocomposites with narrow bandgap materials, such as WO3 and CuO, will improve the performance of electrochemical and optoelectrical devices such as dye-sensitized solar cells and biosensors.
