Excellent Bifunctional Water Electrolysis Activities of α-MoO3/AC Nanocomposites

International Journal of Energy Research, Journal Year: 2024, Volume and Issue: 2024, P. 1 - 13

Published: Jan. 25, 2024

Electrocatalytic water splitting is a cost-effective and environment-friendly technique for producing oxygen hydrogen through the oxygen/hydrogen evolution reaction (OER/HER). Developing highly active stable electrocatalyst, particularly bifunctional electrolysis (i.e., both OER HER), still formidable challenge. Herein, we demonstrated enhanced activities by utilizing molybdenum trioxide-anchored activated carbon (MoO3/AC) nanocomposites. The MoO3/AC samples were fabricated ultrasonication method using sol-gel synthesized MoO3 biomass-derived AC, they displayed nanostreusel-like morphology with spherical nanoparticle-decorated AC nanosheets. For test, nanocomposites exhibited excellent electrocatalytic HER performances low overpotential small Tafel slope values. Through analyzing material characteristics electrochemical properties of MoO3/AC, it was found that superb OER-HER attributed to synergistic effects from hybridization conductive electrochemically α-MoO3. results pronounce possess an aptitude as OER/HER electrocatalyst high-performance electrolysis.

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.
