Anodizing-assisted H2 production is a reliable strategy to achieve carbon-free and efficient green hydrogen production, which is in line with the goal of “dual carbon”. Although significant achievements made in this booming field, these new hydrogen production strategies are still in the early stage and require a significant investment of effort and time. With continuous development in characterization technologies and collaborative efforts of scientists and engineers, we believe that more breakthrough advancements will be realized and extended from laboratory to industry in the future.
