Three‐Dimensional Transition Metal Phosphide Heteronanorods for Efficient Overall Water Splitting

The development of low‐cost electrocatalysts with excellent activity and durability for both the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER) poses a huge challenge in water splitting. In this study, a simple and scalable strategy is proposed to fabricate 3 D heteronanorods on nickel foam, in which nickel molybdenum phosphide nanorods are covered with cobalt iron phosphide (P‐NM‐CF HNRs). As a result of the rational...
