General description

Ferric Phosphate is a tan or yellowish white odorless powder. It is insoluble in water and soluble in mineral acids. It can be prepared by reacting sodium pyrophosphate with ferric citrate. It shows good bioaccesibility.

Application

Iron(III) pyrophosphate can be used:
  • As a cathode material for rechargeable batteries such as Na-ion batteries.
  • To fabricate a hybrid overlayer on the surface of metal oxides to boostphotoelectrochemical solar water splitting reaction.
