The flatness, compactness and high-capacity data storage capability makemetasurfaces well-suited for holographic information recording and generation.However, most of the metasurface holograms are static, not allowing a dynamicmodification of the phase profile after fabrication. Here, we propose anddemonstrate a dynamic metasurface hologram by utilizing hierarchical reactionkinetics of magnesium upon a hydrogenation/dehydrogenation process. Themetasurface is composed of composite gold/magnesium V-shaped nanoantennas asbuilding blocks, leading to a reconfigurable phase profile in a hydrogen/oxygenenvironment. We have developed an iterative hologram algorithm based on theFidoc method to build up a quantified phase relation, which allows thereconfigurable phase profile to reshape the reconstructed image. Such astrategy introduces actively controllable dynamic pixels through ahydrogen-regulated chemical process, showing unprecedented potentials foroptical encryption, information processing and dynamic holographic imagealteration.
