“…Enabling binderless printing would aid in addressing this obvious limitation, both by enabling a higher productivity per volume and eliminating possible adverse side-reactions promoted by binder materials. Different researchers have already made efforts towards realizing this concept, both in the context of 3Dprinting as in conventional shaping technologies (Xu et al, 2012;Elkoro and Casanova, 2018;Wang S. et al, 2019;Lim et al, 2019;Li Z. et al, 2020;Lawson et al, 2021c). In assessing these results, precaution is required as the developments are often highly specific to a certain catalyst within a specific process.…”

Additive manufacturing of catalyst and sorbent materials promises to unlock large design freedom in the structuring of these materials, and could be used to locally tune porosity, shape and resulting parameters throughout the reactor along both the axial and transverse coordinates. This contrasts catalyst structuring by conventional methods, which yields either very dense randomly packed beds or very open cellular structures. Different 3D-printing processes for catalytic and sorbent materials exist, and the selection of an appropriate process, taking into account compatible materials, porosity and resolution, may indeed enable unbounded options for geometries. In this review, recent efforts in the field of 3D-printing of catalyst and sorbent materials are discussed. It will be argued that these efforts, whilst promising, do not yet exploit the full potential of the technology, since most studies considered small structures that are very similar to structures that can be produced through conventional methods. In addition, these studies are mostly motivated by chemical and material considerations within the printing process, without explicitly striving for process intensification. To enable value-added application of 3D-printing in the chemical process industries, three crucial requirements for increased process intensification potential will be set out: i) the production of mechanically stable structures without binders; ii) the introduction of local variations throughout the structure; and iii) the use of multiple materials within one printed structure.

The effective shaping of adsorbents is essential to guarantee a high‐efficiency energetic process in what concerns adsorptive applications. In this way, additive manufacturing is gaining significance in developing structured materials in the field of gas adsorption processes. Additive manufacturing is a promising alternative to the traditional shaping techniques, which possess some drawbacks. This paper aims to review the state‐of‐art of additive manufacturing technologies in the manufacturing of adsorbent structures. To do so, an overview of the existent shaping techniques is done, followed by a summarized description of the leading existing additive manufacturing technologies. Then, the application of additive manufacturing technologies to the development of adsorbent materials and other materials for chemical engineering‐related applications is also reviewed.

“…The investigations of 3D printing in the adsorption applications are mainly focused on the developing of new printable materials for high adsorption rate and large adsorption capa city. [6,177,218,[237][238][239] During the material preparation, the pores in the matrix can be adjusted and the specific surface area are improved, leading to higher adsorption rate and greater adsorption capacity.…”

term solutions are urgently needed before adequate supply of the renewable energy. [1,2] Improvement of efficiency in the energy production and consumption processes is a key factor to address these problems. Meanwhile, the large reaction rate is a key factor to meet the industrial energy requirements. [1][2][3][4][5] Mass transport intensification is an effective method to improve the efficiency and reaction rate in the adsorptions, chemical reactions, and electrochemical reactions, which plays crucial roles in the gas (H 2 , CH 4 , CO 2 , etc.) storage, [6,7] energy conversion, [8] and energy storage. [3,9,10] Recently, novel batteries [2,3,[11][12][13] and microreactors [8,[14][15][16][17][18] for the gas (H 2 , CH 4 , CO 2 , etc.) storage [6,7] and energy conversion [8] have been developed to meet the requirements of high efficiency and rates. In these devices, the mass transport intensification is particularly important to acquire the high selectivity, large reaction rate, great conversion efficiency. [2,8,19,20] The mass transfer steps in the monolithic adsorbents, structured catalysts, and shaped electrodes are similar. Therefore, it is possible to use an identical term to describe the monolithic adsorbents, structured catalysts, and shaped electrodes for convenience to discuss the mass transfer processes. Herein, we use the hierarchically structured components (HSCs) to describe the structures which are comprised of designed channels and matrix between channels, where the matrix is made from functional materials (ceramics, carbon, metals, etc.) with pores in the size from nanometer to sub-millimeters, as illustrated in Figure 1a. In the flow batteries and fuel cells, the assembly of bipolar plate and electrode is regarded as HSC.Generally, the reactants undergo four steps (distribution, adsorption, acceleration, and reaction) in the HSC, as shown in Figure 1b-e. The distribution starts as soon as the reactant flows into the inlet. In this step, the reactant is distributed across the HSC through the designed channels, as shown in Figure 1b. [21,22] Subsequently the fluid is adsorbed by the macropores (>50 nm) which act as buffers for the reactants in the matrix, shown in Figure 1c. [23] As shown in Figure 1d,e, the reactants are accelerated by the mesopores (2-50 nm) and transferred to the micropores (<2 nm) which provide high surface area for the active sites. [23][24][25] After reaction at the active sites, the products are transferred by the mesopores and macropores to the outlet, successively. [26,27] Therefore, the Pursuing high energy efficiency and reaction rate is an effective direction in mitigating the energy and climate crisis. Mass transfer intensification is a powerful approach to enhance the energy efficiency and reaction rate in the energy conversion and storage processes. The nature-inspired channels are outstanding tools to uniformly distribute the reactants, fast remove products, and reduce the diffusion distance for mass transfer intensification in monolithic adsorbents, structured catal...
