This study explores the hydrogen generation potential via water-splitting reactions under UV-vis radiation by using a synergistic assembly of ZnO nanoparticles integrated with MoS2, single-walled carbon nanotubes (SWNTs), and crystalline silicon nanowires (SiNWs) to create MoS2-SiNWs-SWNTs@ZnONPs nanocomposites. A comparative analysis MoS2 synthesized through chemical physical exfoliation methods revealed that chemically exfoliated exhibited superior performance, thereby being selected for all subsequent measurements. The nanostructured materials demonstrated exceptional surface characteristics, specific areas exceeding 300 m2 g−1. Notably, production rate achieved composite comprising 5% 1.7% SiNWs, 13.3% SWNTs at an 80% ZnONPs base was approximately 3909 µmol h−1g−1 500 nm wavelength radiation, marking significant improvement over 40-fold relative pristine ZnONPs. enhancement underscores remarkable photocatalytic efficiency composites, maintaining high rates above 1500 even wavelengths 600 nm. Furthermore, these composites energy storage conversion applications, specifically within rechargeable lithium-ion batteries, investigated. Composites, similar those utilized but excluding address its limited theoretical capacity electrical conductivity, were developed. focus on utilizing as anode Li-ion batteries. strategic combination significantly improved electronic conductivity mechanical stability composite. Specifically, 56% 24% 20% offered cyclic performance values, achieving complete 1000 mA h g−1 after 100 cycles 1 These results illuminate dual utility not only innovative catalysts also advanced technologies, showcasing their in contributing sustainable solutions.
