“…For example, we constructed MoS 2 /COF and metal−organic framework (MOF)/ COF heterojunctions for the photocatalytic removal of organic pollutants. 41,42 Yao et al fabricated a covalent-bond-connected reduced graphene oxide (rGO)/COF heterojunction for enhanced H 2 evolution. 30 The above heterojunctions prepared ZnAgInS is an intriguing visible-light-active photocatalyst with a unique local atomic arrangement and electronic structure, which is favorable for light absorption and charge migration.…”

Covalent organic frameworks (COFs) exhibit visible-light activity for the degradation of organic pollutants. However, the recombination rates of their photoinduced electron− hole pairs are relatively high, limiting their practical application. In this work, we fabricated a 1,3,5-triformylphloroglucinol (Tp) and p-phenylenediamine (Pa-1) (TpPa-1) COF-based heterojunction through coupling the TpPa-1 COF with a ZnAgInS nanosphere via a facile oil bath heating method. The results show that the prepared heterojunction exhibits outstanding catalytic activity for the degradation of high concentrations the antibiotic tetracycline (TC) and the dye rhodamine B (RhB), which is driven by simulated sunlight. Its degradation rates for RhB and TC were 30× and 18× higher than that of the pure TpPa-1 COF, respectively. The greatly enhanced photocatalytic performances can be ascribed to the formed heterojunction with good band-gap match, which promotes the migration and separation of light-induced electrons and holes and increases both light absorbance and the specific surface area. This study introduces an effective and feasible strategy for improving the photocatalytic performances of COFs via subtly integrating TpPa-1 COFs with a ZnAgInS nanosphere into an organic−inorganic hybrid. The results of the photocatalytic experiments indicate that the fabricated hybrid has a potential application in the highly efficient removal of organic pollutants.

“…[121][122][123][124] Based on this view, Zhang et al reported a highly active Fenton-like hybrid photocatalyst of NH 2 -MIL88B@TpPa-1-COF, which was constructed according to the process in Figure 7a. [125] The photocatalytic performance of as-synthesized hybrid materials was evaluated by the photocatalytic degradation of tetracycline (TC). The result showed that NH 2 -MIL88B@TpPa-1-COF (40:63 mg 1,3,5-triformylphloroglucinol, 48 mg p-phenylenediamine, and 40 mg NH 2 -MIL88B) exhibited the highest TC degradation of 86%.…”

Metal–organic frameworks (MOFs) and covalent organic frameworks (COFs) hybrid materials are a class of porous crystalline materials that integrate MOFs and COFs with hierarchical pore structures. As an emerging porous frame material platform, MOF/COF hybrid materials have attracted tremendous attention, and the field is advancing rapidly and extending into more diverse fields. Extensive studies have shown that a broad variety of MOF/COF hybrid materials with different structures and specific properties can be synthesized from diverse building blocks via different chemical reactions, driving the rapid growth of the field. The allowed complementary utilization of π‐conjugated skeletons and nanopores for functional exploration has endowed these hybrid materials with great potential in challenging energy and environmental issues. It is necessary to prepare a “family tree” to accurately trace the developments in the study of MOF/COF hybrid materials. This review comprehensively summarizes the latest achievements and advancements in the design and synthesis of MOF/COF hybrid materials, including COFs covalently bonded to the surface functional groups of MOFs (MOF@COF), MOFs grown on the surface of COFs (COF@MOF), bridge reaction between COF and MOF (MOF+COF), and their various applications in catalysis, energy storage, pollutant adsorption, gas separation, chemical sensing, and biomedicine. It concludes with remarks concerning the trend from the structural design to functional exploration and potential applications of MOF/COF hybrid materials.

“…[ 45 ] Subsequently, other MOF@COF hybrid materials have been reported. [ 32,46 ] However, maybe this growth sequence is not optimal due to the tiny cell size of MOFs and the mesoporous structure of COFs. The common characteristic of these reported MOF/COF hybrid materials is that the performance relies on the interfacial interaction between the MOF and COF layers, where the limited contact interface in MOF@COF hybrid materials restricts their photocatalytic performance for further improvement.…”

The search for building hierarchical porous materials with accelerated photo‐induced electrons and charge‐carrier separation is important because they hold great promise for applications in various fields. Here, a facile strategy of confining metal‐organic framework (MOF) in the 1D channel of the 2D covalent organic framework (COF) to construct a novel COF@MOF micro/nanopore network is proposed. Specifically, a nitrogen‐riched COF (TTA‐BPDA‐COF) is chosen as the platform for in‐situ growth of a Co‐based MOF (ZIF‐L‐Co) to form a TTA‐BPDA‐COF@ZIF‐L‐Co hybrid material. The hierarchical porous structure endows TTA‐BPDA‐COF@ZIF‐L‐Co with superior adsorption capacity. In addition, the integration of TTA‐BPDA‐COF and ZIF‐L‐Co forms a Z‐scheme photocatalytic system, which significantly improved the redox properties and accelerated the separation of photogenerated charges and holes, achieving great improvement in photocatalytic activity. This confinement engineering strategy provides a new idea to construct a versatile molecular‐material photocatalytic platform.
