The combined experimental theoretical calculations reveal that V doping‐induced vacancies lead the formation local electric field within V‐CoP heterojunction‐induced built‐in field, which can jointly accelerate electron transfer charge separation, thereby enhancing reaction kinetics. Moreover, nanotube not only increase electrochemical surface area offer superior mass transfer, but also possess superhydrophilic nature utilization efficiency electrode surfaces. Due these advantages, HNTAs/CF provide distinguished HER OER activity, by employing as bifunctional electrocatalysts, splitting device delivered current density 10 mA cm −2 at low voltage 1.46 maintained its activity without decay 200 h 1 m KOH electrolyte.

Since the radius of sodium ions is larger compared to that lithium ions, it more likely lead structural instability electrode material during embedding and de-embedding process or even trigger collapse. Due ability unsaturated coordination metal–organic framework materials expose metal active centers provide additional sodium-ion binding sites, these have great potential as anode for batteries. In this study, we obtained coordinated Co-terephthalic acid via a simple hydrothermal method using an adjusted metal-to-ligand ratio. The rigid structure benzene ring presence –COO– group ensures both high-strength stability increase in intercalation sites Na ions. Therefore, based on MOF demonstrates long lifespan high capacity 191 mA h g–1 at 100 g–1. preparation pure by constructing provides ideas application MOF-based
