“…However, pure MOFs have drawbacks as photocatalysts, corresponding to a high electron-hole recombination rate and partial adsorption of UV-visible irradiation [49][50][51]. Different groups of materials, including conven-tional semiconductor materials (TiO2, ZnO, CdS, ZnS), carbon-based ma-terials (graphene oxide, g-CN), and even diverse types of MOFs have been used to fabricate active hybrid/composite photocatalysts with en-hanced photocatalytic performance compared to pure MOFs and other parent materials [52][53][54][55]. Among these diverse strategies for developing efficient hybrid/composite photocatalysts, semiconductor@MOF photocatalysts have shown considerable advantages, resulting from the synergistic effect between MOFs and conventional semiconductors [56].…”

In the present work, a direct Z-scheme composite photocatalyst, NH2-MIL-101(Cr)@CuS, with high photodegradation efficiency of Rhodamine B (RhB) degradation in the visible light spectrum, is fabricated through a solvothermal method. It was found that the NH2-MIL-101(Cr)@CuS composite with an appropriate amount of NH2-MIL-101(Cr) exhibited high catalytic performance in the RhB photodegradation. The photocur-rent density and results from the electrochemical impedance spectroscopy (EIS) analysis confirm the promoted photocatalytic activity of the NH2-MIL-101(Cr)@CuS composite compared to the pristine MIL-101(Cr) and CuS nanoparticles, which were supported by the electron lifetime (τn) calculations for the samples. The trapping ex-periments and Mott-Schottky analysis revealed that the superoxide radicals (•O − 2) played an essential role in the photodegradation of RhB and the promoted photocatalytic activity contributed to a direct Z-scheme mechanism between CuS and NH2-MIL-101(Cr). Stability study also shows acceptable results during photocatalytic reaction. Furthermore, Density Functional Theory (DFT) calculations were performed to gain a better understanding of the electronic properties of the NH2-MIL-101(Cr)@CuS nanocomposite. The calculated band structures showed that the nanocomposite has a higher photocatalytic efficiency in the visible region compared to the pristine MIL-101 (Cr) and CuS. The calculated band gap of both the semiconductors and the hybrid nanocomposite confirms the experimental results.

“…In addition, due to topological mismatches between MOFs, various types of MOF‐on‐MOF heterostructures can also be constructed through the comprehensive characteristics of each MOF component. [ 130–132 ] A series of multifunctional MOFs can be combined into the mixing system to develop modular equipment with multiple characteristics. In 2020, Qian, Huang, and co‐workers [ 133 ] reported that an indium‐based MOF acted as a template to directly grow another MOF with totally different crystal lattices on the surface ( Figure a).…”

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.

“…[ 97,98 ] Abdpour et al constructed a new‐type MIL‐100(Fe)@MIL‐53(Fe) hybrid material. [ 99 ] The transformation of electrons and holes between the p‐type and n‐type components of the MIL‐100(Fe)@MIL‐53(Fe) photocatalyst resulted in effective electron–hole separation. Tian et al loaded MIL‐100 (Fe) on MIL‐53 (Fe) as active photocatalyst for degradation of a kind of common microcystin (i.e., Microcystin‐LR).…”

Framework materials, such as metal–organic frameworks (MOFs) and covalent organic frameworks (COFs), offer huge potential for applications in many aspects due to their well‐defined topologies, high crystallinity, inherent porosity, and chemical tunability. One advanced concept of further functionalizing the single framework materials is to construct hybrid frameworks (e.g., MOF‐on‐MOF, MOF‐on‐COF, and COF‐on‐MOF). Herein, different MOF‐based hybrid frameworks with complex compositions and well‐designed structures show excellent properties that cannot be achieved by single framework materials. The synthetic approaches of MOF‐based hybrid frameworks and their related applications are summarized. The opportunities and challenges for MOF‐based hybrid frameworks are also discussed.
