The efficient realization of bifunctional catalysts has immense opportunities in energy conversion technologies such as water splitting. Transition metal dichalcogenides (TMDs) are considered excellent hydrogen evolution owing to their hierarchical atomic-scale layered structure and feasible phase transition. On the other hand, for oxygen evolution, perovskite oxides offer best performance based on rational design flexible compositional structure. A unique way achieve an reaction (HER) (OER)...
