Monovalent-zinc-doped hydrotalcite nano photocatalyst and preparation method and application thereof

The present invention discloses a high-photocatalytic-activity-monovalent-zinc-containing photocatalyst and a preparation method hereof, and belong to the technical field of photocatalytic material preparation. A series of monovalent-zinc-doped zinc-based hydrotalcite nano photocatalysts can be synthesized by use of a reverse microemulsion method for regulating of the type of intercalated metal particles, the monovalent-zinc-doped zinc-based hydrotalcite nano photocatalysts have a unique outer electronic structure, can be excited under the illumination, have good catalytic performance in the aspect of preparation of methane by photocatalytic hydrogenation of carbon monoxide and are low in cost, easy in operation, simple in process and easy in mass production.
