“…Covalent bonds can exist in MOF hybrid materials made using this method but are not as common, so we include relevant examples in the "Covalent Modification" section (hybrids made from ALD and COF-MOF hybrids). Using this technique, metal clusters, metal oxides, graphene oxide, and polymers have been hybridized with MOFs, giving rise to new materials that are useful in gas separation, catalysis, photovoltaics, and proton conducting [52,53,56,[66][67][68][69]. The notation A|B|C is used to represent materials A, B, and C that are hybridized via layer-layer deposition.…”

“…More recently, MOF hybrid membranes were found useful in solar energy harvesting and conversion [52,66,69]. Lee et al prepared a TiO 2 |nanotube|MOF hybrid membrane that showed enhanced photovoltaic performance [66]. A composite film containing TiO 2 nanoparticles and multi-walled carbon nanotubes was first synthesized hydrothermally.…”

The inherent porous nature and facile tunability of metal-organic frameworks (MOFs) make them ideal candidates for use in multiple fields. MOF hybrid materials are derived from existing MOFs hybridized with other materials or small molecules using a variety of techniques. This led to superior performance of the new materials by combining the advantages of MOF components and others. In this review, we discuss several hybridization methods for the preparation of various MOF hybrids with representative examples from the literature. These methods include covalent modifications, noncovalent modifications, and using MOFs as templates or precursors. We also review the applications of the MOF hybrids in the fields of catalysis, drug delivery, gas storage and separation, energy storage, sensing, and others. Crystals 2018, 8, 325 2 of 23to coordinate to other materials. In addition to covalent modifications, MOF hybrids can also be made via noncovalent interactions, such as encapsulation [19,20], layer-by-layer deposition [21], and in situ growth [22]. These methods take advantage of noncovalent interactions between MOFs and the hybridizing species by trapping the species within the MOF pores, layering them on top of the parent MOF, or growing MOFs crystals in situ with the species. Noncovalent modification allows the individual characteristics of the MOF and hybridizing materials to work synergistically in the resultant MOF hybrids while requiring less synthetic efforts than covalent modifications. These methods can be used to achieve materials with MOF coating/protection, multi-layered membranes, and the controlled growth of MOF structures with superior performance than individual parent materials. Finally, hybridizing MOFs through use as either sacrificial templates [23] or precursors [24] utilizes the ordered structure of MOFs to afford porous materials with high surface areas and uniform pore sizes. This method eliminates the metal node and/or the organic linker, leaving behind only the newly synthesized materials with the inherited uniform nanoframe of the template/precursor MOF.In this review, we discuss each hybridization method with representative MOF hybrids from literature, as well as the hybrid materials' superior performances and applications. At the end of this review, we also summarize all reported MOF hybrid materials. Crystals 2018, 8, x FOR PEER REVIEW 2 of 22

“…Nevertheless, using MOFs for fabricating full solar cell devices is rarely investigated. More recently, MOF thin films have been demonstrated as sensitizers for solar radiation harvesting in a TiO 2 -based liquid junction solar cells [12] . The device had an I sc of 1.25 mA cm -2 , V oc of 0.49 V, fill factor of 0.43, and power conversion efficiency of 0.26%.…”

“…Besides, carbon nanotubes (CNTs), tubular analogue to graphene sheets, may be an alternative carbon to facilitate MOFs adsorbing target compounds and to enhance MOFs photocatalytic activity under visible light (Cong et al, 2011;You et al, 2013). However, rare studies reported the addition of CNTs into MOFs and evaluated its effect on adsorption in water and photocatalytic activity in the literature (Anbia and Sheykhi, 2013;Lee et al, 2014). Therefore, in this study, we investigate the effects of amine, CNTs and reduced graphene oxide (RGO) on MOF's adsorptive and photocatalytic performances to remove dyes from water.…”

To investigate effects of modification of MOFs on removal of acid dyes via adsorption and photodegradation, zirconium-based MOF, UiO-66, and its derivatives were synthesized. UiO-66 derivatives were prepared by using amine (NH2)-containing ligand and incorporating carbon nanotubes (CNTs) and reduced graphene oxide (RGO). During the synthesis UiO-66-NH2, UiO-66-CNT and UiO-66-RGO, were obtained, respectively. While UiO-66-NH2 showed the enhanced adsorption capacity for acid dyes owing to the electrostatic attraction, CNTs were found to be the most effective addition to enhance the adsorption of acid dyes. However, the addition of RGO in UiO-66 (to form UiO-66-RGO) exhibited the highest removal efficiency via photodegradation compared to UiO-66 and other derivatives probably attributed to its unique layered morphology. The presence of NH2, CNTs and RGO not only significantly improved the adsorption capacity for acid dyes but also enabled these UiO-66 derivatives to exhibit photocatalytic activity under visible light irradiation.
