Phase Engineering Modulates the Electronic Structure of the IrO 2 /MoS 2 Heterojunction for Efficient and Stable Water Splitting

The engineering of dual-functional catalytic systems capable of driving complete water dissociation in acidic environments represents a critical requirement for advancing proton exchange membrane electrolyzer technology, yet significant challenges remain. In this work, we investigate an IrO2/MoS2/CNT heterostructure catalyst demonstrating enhanced bifunctional performance for both the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) under acidic conditions. Strategic incorporation of IrO2 into the MoS2/CNT heterojunction induces a partial phase transformation from 2H to the metastable 1T configuration in MoS2, thereby modulating the electronic structure of IrO2 and improving the catalytic…
