Summary: This work presents the fabrication of polyallylamine-encapsulated Ir metallene with defects and a porous structure (Ir@PAH metallene) through a one-step wet chemical reduction method. The Ir@PAH metallene exhibits excellent performance in the hydrogen evolution reaction (HER), with low overpotential, a low Tafel slope, and almost no activity decay after stability test. The abundant defects and pores, as well as the nanosheet structures of Ir@PAH metallene, provide a large specific surface area, high conductivity, and efficient mass transport/diffusion. The surface-functionalized PAH molecules play a crucial role in modulating the electronic structure and capturing hydrogen ions, which is beneficial for HER in acidic media.
