Abstract

In this work, we demonstrated a general strategy for the preparation of a series of uniform Ag₂WO₄/AgX (X = Cl, Br, I) hybrid nanorods by a facile in-situ anion exchange reaction occurring at room temperature between pregrown Ag₂WO₄ nanorods and different X^- ions in water. Compared with Ag₂WO₄ nanorods, further investigation has revealed that the as-prepared hybrid nanorods possess signi?cantly enhanced photocurrent response and photocatalytic activity in degrading methyl orange (MO) under visible-light irradiation. In particular, the Ag₂WO₄/AgBr hybrid nanorods exhibit the highest photocatalytic activity among the three kinds of samples. The active species tests indicate that superoxide anion radicals and photogenerated holes are responsible for the enhanced photocatalytic performance.
