"Bottom-up" additive manufacturing (AM) is the technology whereby a digitally designed structure is built layer-by-layer, i.e., differently than by traditional manufacturing techniques based on subtractive manufacturing. AM, as exemplified by 3D printing, has gained significant importance for scientists, among others, in the fields of catalysis and separation. Undoubtedly, it constitutes an enabling pathway by which new complex, promising and innovative structures can be built. According to recent studies, 3D printing technologies have been utilized in enhancing the heat, mass transfer, adsorption capacity and surface area in CO adsorption and separation applications and catalytic reactions. However, intense work is needed in the field to address further challenges in dealing with the materials and metrological features of the structures involved. Although few studies have been performed, the promise is there for future research to decrease carbon emissions and footprint. This review provides an overview on how AM is linked to the chemistry of catalysis and separation with particular emphasis on reforming reactions and carbon adsorption and how efficient it could be in enhancing their performance.
“自下而上”的增材制造（AM）是一种通过逐层构建数字设计结构的技术，即与基于减法制造的传统制造技术不同。以3D打印为例的增材制造在催化和分离等领域对科学家等群体而言已变得极为重要。毫无疑问，它构成了一条可行途径，通过此途径可以构建新的复杂、有前景和创新性的结构。根据最近的研究，3D打印技术已被用于提高CO吸附与分离应用以及催化反应中的传热、传质、吸附容量和表面积。然而，该领域仍需要大量工作来应对处理相关结构的材料和计量特征方面的进一步挑战。尽管进行的研究较少，但未来研究有望减少碳排放和足迹。本综述概述了增材制造如何与催化和分离化学相关联，特别强调重整反应和碳吸附，以及它在提高其性能方面的效率如何。
