Developing a semiconductor-based heterostructure photoanode is crucial in improving the photoelectrocatalytic (PEC) efficiency for degrading refractory organic pollutants. Nevertheless, PEC performance of photoanodes usually restricted by electron/hole pair recombination, oxygen evolution, and slow electron transfer. Herein, novel CoO@BiVO4 nanowire array film (Ti/CoO@BiVO4) with n-type semiconductor characteristics was prepared via straightforward hydrothermal method. The optimized Ti/CoO@BiVO4 electrode exhibited excellent decolorization active brilliant blue KN-R (∼92.8%) long-term stability, outperforming recent reports. insight reason enhancing degradation electrodes can be attributed to large electrochemical area, low charge transfer resistance, negative flat band potential. formation type-II investigated between CoO BiVO4 further promote generation separation pairs, indicating that has potential water ability superior service life.

This study explores a novel photoelectrode made from combination of copper oxide (CuO), polyaniline (PANI), and gold nanoparticles (Au NPs) for efficient hydrogen production in photoelectrochemical (PEC) water splitting. The Au/PANI/CuO is fabricated using cost-effective methods, ensuring practical applications. research evaluates the photoelectrode's morphology, structure, efficiency, stability to optimize its performance PEC reactions. Integrating Au, PANI, CuO nanomaterials improves charge transfer, reduces resistivity, minimizes recombination, resulting significantly enhanced efficiency. Scanning electron microscopy (SEM) reveals that film has rough texture with non-uniform particles, while PANI/CuO exhibits agglomerates interconnected PANI nanofibers. Au NPs are evenly distributed across film, diameters ranging 5 60 nm. Energy dispersive X-ray (EDX) analysis approves presence each element desired proportions, validating successful fabrication photoelectrode. light absorption properties due surface plasmon resonance (SPR) effect interaction between CuO. demonstrates remarkable 300-fold increase photocurrent density (J_ph) compared pure CuO, achieving maximum 15 mA/cm² at -0.39 V vs. RHE.
