Abstract
![]()
The chemical functionalization of
2D exfoliated black phosphorus
(2D BP) continues to attract great interest, although a satisfactory
structural characterization of the functionalized material has seldom
been achieved. Herein, we provide the first complete structural characterization
of 2D BP functionalized with rare discrete Pd2 units, obtained
through a mild decomposition of the organometallic dimeric precursor
[Pd(η3-C3H5)Cl]2. A multitechnique approach, including HAADF-STEM, solid-state NMR,
XPS, and XAS, was used to study in detail the morphology of the palladated
nanosheets (Pd2/BP) and to unravel the coordination of
Pd2 units to phosphorus atoms of 2D BP. In particular,
XAS, backed up by DFT modeling, revealed the existence of unprecedented
interlayer Pd–Pd units, sandwiched between stacked BP layers.
The preliminary application of Pd2/BP as a catalyst for
the hydrogen evolution reaction (HER) in acidic medium highlighted
an activity increase due to the presence of Pd2 units.
