Sep 29, 2011· Iron phosphate is used as a base for paint or powder coat to enhance adhesion. Unlike both zinc and manganese phosphates, in which the metal cation is found in the phosphating solution, the cation of the iron phosphate coating is contributed by the basis metal. The phosphating solution contains alkali metal phosphate and accelerators.

Phosphate minerals contain the tetrahedrally coordinated phosphate (PO 4 3−) anion along sometimes with arsenate (AsO 4 3−) and vanadate (VO 4 3−) substitutions, and chloride (Cl −), fluoride (F −), and hydroxide (OH −) anions that also fit into the crystal structure.. The phosphate class of minerals is a large and diverse group, however, only a few species are relatively common.

Herein, the growth of a partial iron phosphate (FeP) shell with Fe 2+ ions on citrate-capped AuNPs boosted the activity of the AuNPs by up to 20-fold. The FeP-enhanced activity was demonstrated on AuNPs of different sizes, and gold nanostars. When the FeP layer is thick enough to block the access to the Au/FeP interface, the activity was inhibited.
