Simply preparing oriented and defect‐free molecular‐sieve films have been a long‐standing challenge both in academia and industry. Most of the early works focus on the careful and multiple controls of the seeds layer or synthesis conditions. Herein, we report a one‐step in situ electrochemical ionothermal method that combines a controllable electric field with ionic liquids. We demonstrate that an in‐plane oriented and defect‐free AEL (one molecular‐sieve framework type) molecular‐sieve film was obtained using an Al electrode as the Al source. The excellent corrosion‐resistant performance of the film makes this technology promising in multiple applications, such as anti‐corrosion coatings.
