Trimetallic spinel NiCo<sub>2−<i>x</i></sub>Mo<sub><i>x</i></sub>O<sub>4</sub> oxygen evolution catalyst enabling bias-free solar water splitting with inverted perovskite solar cells
Partial Mo 6+ leaching selectively activates Ni 2+ in NiCo 2− x Mo x O 4 , forming NiOOH, to enhance OER. When integrated into a water electrolyzer powered by a p-i-n perovskite solar cell, the system enables bias-free solar H 2 production at 8.8% efficiency.
