Abstract
The development of green hydrogen through anion exchange membrane water electrolysis (AEMWE) is essential for achieving carbon neutrality. Developing non-precious-metal catalysts for the hydrogen evolution reaction (HER) is crucial for the commercialization of AEMWE. In this study, Ni-CeO₂/C catalysts were synthesized via a co-precipitation method and a reduction heat treatment..... More
