Key Points

The research aims to enhance the efficiency and stability of proton exchange membrane water electrolysis using a novel cobalt oxide catalyst.
Development of a low-cost Co3O4-based catalyst with oxygen vacancies and Nd-insertion (Nd-CoOx)
Characterization through in-situ methods such as X-ray absorption spectroscopy and Raman spectroscopy
Performance assessment in acidic oxygen evolution reaction and water electrolysis.
Achieved a low overpotential of 317 mV at 10 mA cm^-2 for oxygen evolution
Catalyst maintained stability over 800 hours with minimal degradation
Nd-CoOx delivered a performance of 200 mA cm^-2 at a low cell voltage of 1.69 V
