Photocatalytic dehydrogenation of
formic acid is a promising strategy
for H2 generation. In this work, we report the use of crystalline
iron phosphide (FeP) nanoparticles as an efficient and robust cocatalyst
on CdS nanorods (FeP@CdS) for highly efficient photocatalytic formic
acid dehydrogenation. The optimal H2 evolution rate can
reach ∼556 μmol·h–1 at pH 3.5,
which is more than 37 times higher than that of bare CdS. Moreover,
the photocatalyst demonstrates excellent stability; no significant
decrease of the catalytic activity was observed during continuous
testing for more than four days. The apparent quantum yield is ∼54%
at 420 nm, which is among the highest values obtained using noble-metal-free
photocatalysts for formic acid dehydrogenation. This work provides
a novel strategy for designing highly efficient and economically viable
photocatalysts for formic acid dehydrogenation.
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.
