Hydrogen ion has been extensively studied as a charge carrier in electrochemical energy storage devices due to its minimal ionic radius and abundant reserves. Among various candidate materials, molybdenum trioxide (MoO3) stands out promising electrode material owing excellent chemical stability ultrahigh theoretical capacity. However, practical application is hindered by narrow potential window hydrogen-ion low operating voltage caused aqueous electrolyte decomposition. In this study, MoO3 nanoribbons with significant number of oxygen vacancies were synthesized via simple hydrothermal method, which exhibit notable backward shift the hydrogen evolution potential, three-proton intercalation/deintercalation process, then very noticeable enhancement capacity during testing electrolyte. It was also found that tungsten(W) doping specific amount can enrich further enhance their performance. Remarkably, W-doped nominal molar ratio 3% demonstrate an exceptional 390.8 mA h/g at current density 100 C (40 A/g). This study might highlight impact vacancy on microstructures properties provide valuable insights for design development high-performance materials batteries.
