Boosting and stabilizing oxygen evolution reaction through Ru single atoms anchored amorphous NiMoO_x electrocatalyst.

ABSTRACT: Efficient and durable electrocatalysts for the oxygen evolution reaction (OER) are essential for advancing water splitting technologies, which enable sustainable hydrogen production. The integration of amorphous oxide supports with metal single atoms offers a promising strategy to precisely tuning the electronic structure and improving the exposure of active sites. Here, we report an amorphous NiMoO_x support anchored with Ru single atoms (denoted as a-RNMO), which achieves a low cell voltage of 1.78 V at 1 A cm^-2 and noteworthy durability in an anion exchange membrane water electrolyzer. Time-resolved operando Quick X-ray absorption spectroscopy reveals rapid Mo leaching followed by structural reconstruction, culminating in the NiOOH formation. Theoretical calculation
