Intercalation Synthesis of Prussian Blue Analogue Nanocone and Their Conversion into Fe-Doped Co<sub><i>x</i></sub>P Nanocone for Enhanced Hydrogen Evolution
Compared with the
monometallic phosphides, bimetallic phosphides
can further improve the catalytic performance for hydrogen evolution
reaction (HER). As such, the rational design and facile synthesis
of bimetallic-based phosphides with well-controlled architectures
and compositions is of scientific and technological importance. In
this work, Fe–Co Prussian blue analogue (PBA) nanocones (NCs)
have been successfully fabricated via an intercalation reaction strategy
by utilizing layer structured α-CoÂ(OH)<sub>2</sub> NCs as self-sacrificing
templates. After calcination and phosphorization process, Fe–Co
PBA NCs can be converted to Fe-doped Co<sub><i>x</i></sub>P NCs without obvious shrinkage. Electrochemical tests show that
Fe incorporation can effectively promote the electrocatalytic activities
of Co<sub><i>x</i></sub>P. This simple and effective method
will be of benefit for the development of other functional Co-based
bimetallic compounds. Furthermore, this strategy can possibly be extended
to fabricate a series of PBA materials with special structure and
novel morphology, which can serve as a promising platform for diverse
applications, especially in energy storage and conversion
