Additive manufacturing (AM) presents a promising opportunity for the innovative design and production of structured catalytic materials. Given the critical role of catalysts in industrial catalytic processes, AM has the potential to contribute to the development of improved catalysts by reducing activation energy and enhancing selectivity. Conventional synthesis methods limit the choice of structural materials and composition for producing monoliths. Additionally, the deposition of catalytic compounds is also restricted by commonly applied techniques that may require prior coverage or treatments to improve adherence or do not achieve a homogenous coat. Moreover, production is limited to monoliths with straight and parallel channels. However, this format drives to laminar regime flow thus restricting the radial mass and heat transfer. Conversely, AM allows the production of a wider variety of compositions and more complex structures that have proven to rise their effectiveness by increasing reagents‐catalyst interaction, making catalytic processes more cost‐effective. Therefore, in this review an outline of the recent progress of AM methods in the development of monolithic catalysts is presented focusing on the requirements, advantages, and disadvantages of each technique, hence providing a practical overview of their novel opportunities to overcome current limitations in catalyst synthesis.

彻底改变整体式催化剂：通过计算机辅助制造实现设计控制的突破

增材制造（AM）为结构化催化材料的创新设计和生产提供了一个充满希望的机会。鉴于催化剂在工业催化过程中的关键作用，增材制造有潜力通过降低活化能和提高选择性来促进改进催化剂的开发。传统的合成方法限制了用于生产整体材料的结构材料和组成的选择。此外，催化化合物的沉积还受到常用技术的限制，这些技术可能需要预先覆盖或处理以提高粘附性或无法获得均匀的涂层。此外，生产仅限于具有直通道和平行通道的整体材料。然而，这种形式驱动层流流，从而限制径向质量和热传递。相反，增材制造可以生产更多种类的组合物和更复杂的结构，事实证明，这些组合物可以通过增加试剂与催化剂的相互作用来提高其有效性，从而使催化过程更具成本效益。因此，在这篇综述中，概述了增材制造方法在整体式催化剂开发中的最新进展，重点关注每种技术的要求、优点和缺点，从而提供了克服当前催化剂局限性的新机会的实际概述。合成。
