Hydrogen production through the use of renewable raw materials and renewable energy is crucial for advancing its applications as an energy carrier. In this study, we fabricated a solid oxide solution of Cu and Ni within a confined pore space, followed by a partial reduction, to produce a highly efficient catalyst for ethanol steam reforming (ESR). At 300 °C, EtOH is completely converted, a H 2 yield of approximately 5 mol per mol is achieved, and CO 2 is the main carbon‐containing product. This demonstrates that H 2 production from bioethanol is an efficient and sustainable approach. Such a highly efficient ESR catalyst is attributed to the ability of the metal–oxide interface to facilitate the transformation of CH x adspecies from acetaldehyde decomposition into methoxy‐like adspecies, which are reformed readily to produce H 2 and consequently reduce CH 4 formation.
