Prussian blue analogue (PBA)-derived
porous ternary metallic nitride
(Ni3FeN) has been successfully prepared through a simple
two-step oxidation–rapid nitridation process and used for the
photocatalytic hydrogen evolution reaction. The porous structure of
the Ni3FeN nanocube contributes to the adsorption of the
Eosin-Y photosensitizer, while also ensuring sufficient exposed active
sites. This aids in improved reaction kinetics of the photocatalytic
hydrogen evolution reaction. Moreover, the superior conductivity of
ternary Ni3FeN promotes the transfer of charge carriers
excited from Eosin-Y, which also promotes the photocatalytic performances
of Ni3FeN/Eosin-Y systems. When used with Eosin-Y as a
dye photosensitizer, the porous ternary Ni3FeN nanocube
exhibits superior performance, which is more than 3.45, 3.83, and
1.31 times higher than that of the PBA, NiFeO
x
, and Prussian blue-derived Fe3N samples. The Ni3FeN catalyst exhibits an optimal H2 production rate of
16.96 mmol g–1 h–1, with an apparent
quantum efficiency of ∼3.03% at 520 nm excitation wavelength.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
