Abstract
A conjugated microporous polymer is in situ electropolymerized to form a basis for immobilization of a molecular catalyst onto glassy carbon. A cost‐effective molecular catalyst is then grafted onto the polymer by π–π interactions as evidenced by X‐ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), and UV–vis spectra. The prepared cathode represents a high activity toward hydrogen evolution (109 100 turnovers in 2 h) in mild acidic aqueous solutions with a ≈100% faradaic efficiency. The cathode also shows a very good stability. In total, this article introduces a facile means to design and prepare a hydrogen generation cathode using widely available and inexpensive materials.
