“…9,[12][13][14][15] To summarize these active research fields, several previous reviews have briefly introduced MOF-on-MOF under hierarchical MOF architecture. [16][17][18][19] Recently, Liu et al 15 and Xu et al 20 provided comprehensive information regarding MOF-on-MOF, categorizing synthetic approaches and applications, in particular. In this review, however, we specifically focus on the fascinating potential applications of MOF-on-MOF, and in the actively studied fields of separation, catalysis, and sensing (Scheme 1).…”

Metal-organic frameworks (MOFs) are porous crystalline materials with a high tunability. To improve the functionality of the original frameworks, several strategies, such as the use of different metal cations and organic ligands and post-synthetic modification, have been developed, enabling the use of MOFs in numerous practical applications in various fields. Recently, another approach, i.e., MOF-on-MOF architecturing, has been actively studied by combining two or more MOFs into a composite. MOF-on-MOF materials not only possess the intrinsic properties of each MOF but also exhibit unprecedented synergism within a single system, resulting in a considerable potential for various applications. This review summarizes the interesting areas of application of MOF-on-MOF architectures into three categories: separation, catalysis, and sensing. In particular, the synergism occurring within such MOF-on-MOF architectures is discussed.

“…With the rapid development of consumable electronics and power facilities, the public has called for an extensive research into energy technologies. [1][2][3] Among them, zinc-air batteries (ZABs) have been potential alternatives due to their advantages of high energy density, environment friendliness and operation safety. [4][5][6] However, the complex and sluggish kinetics of oxygen reduction and evolution reactions (ORR/OER) at air electrodes during the discharge/charge process severely limit its electrochemical properties and lead to low power density and unsatisfactory cyclability.…”

Integrating high-efficiency oxygen electrocatalyst directly into air electrodes is vital for zinc-air batteries to achieve higher electrochemical performance. Herein, a self-standing membrane composed of hierarchical cobalt/ nanocarbon nanofibers is fabricated by the electrospinning technique. This hybrid membrane can be directly employed as the bifunctional air electrode in zinc-air batteries and can achieve a high peak power density of 304 mW cm −2 with a long service life of 1500 h at 5 mA cm −2 . Its assembled solid-state zinc-air battery also delivers a promising power density of 176 mW cm −2 with decent flexibility. The impressive rechargeable battery performance would be attributed to the self-standing membrane architecture integrated by oxygen electrocatalysts with abundant cobalt-nitrogen-carbon active species in the hierarchical electrode. This study may provide effective electrospinning solutions in integrating efficient electrocatalyst and electrode for energy storage and conversion technologies.

“…MOF‐on‐MOF composites dexterously combine the characteristics of the dual MOFs and ternary MOFs to obtain the target materials with various or improved properties under the synergistic reaction. [ 75–79 ] Recently, the Xu group [ 80 ] from Yangzhou University reported in 2020 that two important approaches, namely epitaxial growth and post‐synthetic modification, were applied to construct MOF‐on‐MOF hybrids. Meanwhile, Yu and co‐workers [ 81 ] summarized the MOF‐on‐MOF synthetic strategies and unique structure/composition regulation in 2021.…”

Multiporous metal‐organic frameworks (MOFs) have emerged as a subclass of highly crystalline inorganic‐organic materials, which are endowed with high surface areas, tunable pores, and fascinating nanostructures. Heterostructured MOF‐on‐MOF composites are recently becoming a research hotspot in the field of chemistry and materials science, which focus on the assembly of two or more different homogeneous or heterogeneous MOFs with various structures and morphologies. Compared with one single MOF, the dual MOF‐on‐MOF composites exhibit unprecedented tunability, hierarchical nanostructure, synergistic effect, and enhanced performance. Due to the difference of inorganic metals and organic ligands, the lattice parameters in a, b, and c directions in the single crystal cells could bring about subtle or large structural difference. It will result in the composite material with distinct growth methods to obtain secondary MOF grown from the initial MOF. In this review, the authors wish to mainly outline the latest synthetic strategies of heterostructured MOF‐on‐MOFs and their derivatives, including ordered epitaxial growth, random epitaxial growth, etc., which show the tutorial guidelines for the further development of various MOF‐on‐MOFs.
