Trace amounts of Ru-doped Ni–Fe oxide bone-like structures <i>via</i> single-step anodization: a flexible and bifunctional electrode for efficient overall water splitting

Abstract

A trace amount of Ru-doped Ni–Fe oxide film with an <italic>in situ</italic> formed 3D bone-like structure is an outstanding, efficient, durable, and flexible bifunctional catalyst for water splitting.
