%X 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 Cu2+ active sites (2.1 ×
106 per μm2), 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 Cu2+ active sites
were proposed and validated by density functional theory calculations.
