Bioethanol, derived from agricultural sources, is considered as one of the promising sustainable alternatives to fossil fuels. Indeed, several catalytic routes can be used to convert bioethanol to valuable chemicals and materials, particularly by employing a zeolite as a catalyst. However, it still suffers from using a conventional zeolite due to the rapid deactivation of the catalyst from pore blockage and acid-site poisoning during bioethanol conversion. To address this challenge, hierarchical zeolites have been explored to enhance molecular diffusion and optimize acidic characteristics, eventually improving catalytic activity and stability. This review provides a comprehensive overview of recent advancements and perspectives in utilizing hierarchical zeolites for bioethanol upgrading. We emphasize the synthesis of hierarchical zeolites and their applications in bioethanol conversion to high-value-added chemicals, such as ethylene, acetaldehyde, butadiene, aromatics, jet fuels, and carbon materials. We highlight both the advantages and challenges associated with hierarchical zeolites as well as the potential for further development of this novel type of catalyst in bioethanol conversion processes.
