Abstract

Fe4(OH)3(PO4)3 microcrystals are successfully synthesized by a simple hydrothermal method. Due to a possible self-etching mechanism, different morphologies of Fe4(OH)3(PO4)3 microcrystals are obtained. Several reactions with different temperatures and times are performed to confirm the supposed self-etching mechanism. Moreover, as a result of their different micro/nanostructures, these microcrystals present different photocatalytic activities for visible-light-driven photodegragadation of methylene blue.

Keywords: ferric phosphate hydroxide; hydrothermal synthesis; methylene blue; microcrystals; photocatalysis.
