“…The increased selectivity of the hydrogenation reaction was attributed to special pore windows inside the ZIF‐8 shells. A similar result was reported by using void@HKUST‐1/Pd@ZIF‐8 hollow catalysts in the hydrogenation reaction …”

“…Additionally, noble‐metal nanoparticles (NPs) are easily introduced into the MOF shells to build composite structures by the exterior‐template method. For example, sulfonated PS spheres were successfully adopted as the templates to construct a double‐shelled hollow structure, void@HKUST‐1/Pd@ZIF‐8, in which Pd NPs were uniformly embedded in the inner HKUST‐1 shell …”

The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adma.201803291.Hollow metal-organic framework (MOF) micro/nanostructures and their derivatives are attracting a great amount of research interest in recent years because their hierarchical porous structures not only provide abundant, easily accessed metal sites but also endow 3D channels for rapid mass transport. As a result, they demonstrate significant advantages in many applications including catalysis, gas sensors, batteries, supercapacitors, and so on. Nevertheless, studies on hollow MOFs and their derivatives are still at the beginning of this field, and the relationship between their structures and application performances is not yet reviewed comprehensively. Herein, the synthetic strategies and practical applications of hollow micro/nanostructured MOFs and their derivatives are summarized, and their corresponding prospects are also discussed.

“…Generally, the transformation of a carbonyl group into a methyl group can proceed via three pathways: (1) direct hydrogenolysis of CO bond, (2) hydrogenation of CO bond and then dehydration, and (3) hydrogenation of CO bond and then hydrogenolysis of CO . For the first pathway, direct hydrogenolysis of CO bond would not generate HMP.…”

Highly dispersed copper nanoparticles (Cu NPs) supported on activated carbon (AC) are effectively synthesized by one-pot carbothermal method at temperature range of 400-700 °C. The X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, and Brunauer-Emmett-Teller analysis reveal that Cu NPs with diameters of 20-30 nm are evenly anchored in carbon matrix. The 15 wt%-Cu/AC-600 catalyst (derived at 600 °C) exhibits best bifunctional catalysis of aqueous-phase hydrodeoxygenation (HDO) and organic-phase transfer-hydrogenation reaction (THR) to selectively transform vanillin to 2-methoxy-4-methylphenol (MMP). In HDO of vanillin, the as-prepared catalyst achieves a 99.9% vanillin conversion and 93.2% MMP selectivity under 120 °C, 2.0 MPa H within 5 h. Meanwhile, near-quantitative vanillin conversion and 99.1% MMP selectivity are also obtained under 180 °C within 5 h in THR of vanillin by using 2-propanol as hydrogen donor. The transforming pathways of vanillin are also proposed: vanillin is transformed into MMP via intermediate of 4-hydroxymethyl-2-methoxyphenol in HDO case and by direct hydrogenolysis of vanillin in THR course. More importantly, the activity and the selectivity do not change after 5 cycles, indicating the catalyst has excellent stability. The Cu-based catalyst is relatively cheap and preparation method is facile, green, and easy scale-up, thus achieving a low-cost transformation of biomass to bio-oils and chemicals.

“…Few researches notice the precise control over the distribution and diffusion of nanoparticles in MOFs. Due to the molecular sieving effects resulted from the porous character of MOFs, metal nanoparticles@MOF (MNPs@MOF), such as the yolk–shell structure based on ZIF‐8, exhibits promising catalytic activities . However, the molecular diffusion rate has been kept at a low level due to the narrow MOF channels, which would bring about poor reaction rate.…”

Metal-organic frameworks (MOFs) have been intensely studied for the past few decades as an enormous family of highly tunable porous materials with promisingly applicable functionalities in adsorption, separation, catalysis, sensing, electrochemistry, and a great number of emerging purposes. As a classic MOF, zeolitic imidazolate framework-8 (ZIF-8) is conventionally one of the very few MOF members that has been commercialized with considerable production. Its large surface areas, well-controlled porosity and textural tunability, high thermal and chemical stability allows researchers to conduct enormous studies on derivatives of MOFs and MOF-related composites using ZIF-8 as the prior sampling substance. However, despite all the remarkable discoveries leading almost all aspects of future applications of MOFs, no specific work has yet been done to recapitulatively summarize these achievements centered around the current limitations and prospects of their common demonstrator, ZIF-8, for its integration into real processes or applications, thus drastically blinding people from distinctly observing the inner correlations among all these researches. To wipe out this confusion and make the usages of ZIF-8 both in applicable systems and upfront explorations much more understandable and convenient to all researches of relevant application areas, this review aims at offering clear guidance, experience, and references by meticulously categorizing published works associated with ZIF-8.
