Green hydrogen produced via water electrolysis powered by renewable energy sources promises the decarbonization of large sectors of the economy. Despite alkaline environments that enable use of non-noble, abundant materials, state-of-the-art anion exchange membrane water electrolyzers (AEMWEs) uses noble-metal-based catalysts. Developing non-noble-metal-based anodes would enhance the competitiveness of AEMWEs. Herein, an anode fabricated by hydrothermal deposition of binder-free NiFe-LDH onto Raney Ni (RNi) substrates is described. The introduced platinum-group-metal-free AEMWEs display high performance of 1 A cm–2 at 1.9 V cell voltage. Physicochemical characterization highlights the successful combination of NiFe-LDH with RNi applying a scalable synthesis offering feasibility to fabricate active and durable electrodes for AEMWEs.
