Key Points

The aim is to enhance RuO2's catalytic activity and stability for water splitting by incorporating Gd to modify its lattice structure.
Lattice constants of RuO2 were tuned through Gd doping.
Performance of Gd doped RuO2 catalysts was evaluated in PEMWE (Proton Exchange Membrane Water Electrolysis).
Measurements were made to assess overpotential and durability of the catalysts.
Gd0.08Ru0.92O2 exhibited significantly lower overpotential compared to non-doped RuO2.
The catalyst demonstrated excellent durability over extended use, indicating high stability during water splitting.
Optimization of Ru-O covalency contributed to improved catalytic performance.
