Due to the extremely
high number of accessible active sites and
short diffusion path, porous coordination polymer (PCP) nanosheets
have demonstrated a variety of promising applications, especially
for energy conversion and mass transfer. However, the development
of chemically stable PCP nanosheets with dense active sites and large
lateral size is a great challenge in terms of feasible considerations.
Herein, we first designed and prepared a kind of chemically stable
PCP nanosheets via a bottom-up and a top-down integral strategy. Featuring
densely exposed and periodic Cu<sup>2+</sup> active sites (2.1 ×
10<sup>6</sup> per μm<sup>2</sup>), as well as ultrathin nature
(5 nm) and significant pores (18 Å), this nanosheet demonstrated
remarkable performance of electrocatalytic hydrogen evolution. Furthermore,
one plausible process and the effect of Cu<sup>2+</sup> active sites
were proposed and validated by density functional theory calculations.
