Abstract: The development of non-platinum-based electrocatalysts for hydrogen evolution reaction (HER) is always a meaningful and hot research issue as it is an effective and promising route to produce clean hydrogen energy and alleviate the energy crisis. Herein, a vinylene-linked covalent organic framework (PY-SE- COF) was constructed by Knoevenagel reaction and served as palladium ions (Pd2+) supports with Pd content of 16.8 wt %. PY-SE–COF–Pd can be applied as an efficient electrocatalyst for hydrogen evolution reaction (HER) in acidic electrolyte with an overpotential of 128 mV at the current density of 10 mA cm−2, outperforming the electrocatalytic activity of individual PY-SE-COF and PdCl 2. This is the first Pd2+ coordinated COFs electrocatalytic system for HER and the current study proves that vinylene-linked COFs are promising platforms for the design and construction of composite pyrolysis-free electrocatalysts for clean energy conversion. A Pd2+ modified vinylene-linked covalent organic framework was constructed and exhibited efficient electrocatalytic performance for hydrogen evolution reaction in acidic media. [Display omitted] • Pd2+ modified vinylene-linked covalent organic frameworks (PY-SE–COF–Pd) was designed and synthesized. • PY-SE–COF–Pd was the first Pd coordinated COF system for hydrogen evolution reaction (HER). • PY-SE–COF–Pd exhibited effieient HER performance with an overpotential of 128 mV at 10 mA cm−2, outperforming the individual PY-SE-COF and PdCl 2. • Pd0 formed by in situ electroreduction in PY-SE–COF–Pd may play a key role in the HER process.
