“…Hence, algae bio-oil cannot be used as transportation fuel without removing these fatty acids. For this, Fang et al 262 developed a facile one-pot strategy to convert palmitic acid into hexadecane over a bifunctional MOF catalyst, consisting of encapsulated phosphotungstic acid inside the MOF structure of PdCu@Fe III -MOF-5. The developed catalyst shows an improved acidity and completely converts palmitic acid with a high selectivity to hexadecane.…”

Efficient transformation of biomass to value-added chemicals and high-energy density fuels is pivotal for a more sustainable economy and carbon-neutral society. In this framework, developing potential cascade chemical processes using functionalised heterogeneous catalysts is essential because of their versatile roles towards viable biomass valorisation. Advances in materials science and catalysis have provided several innovative strategies for the design of new appealing catalytic materials with well-defined structures and special characteristics. Promising catalytic materials that have paved the way for exciting scientific breakthroughs in biomass upgrading are carbon materials, metal-organic frameworks, solid phase ionic liquids, and magnetic iron oxides. These fascinating catalysts offer unique possibilities to accommodate adequate amounts of acid-base and redox functional species, hence enabling various biomass conversion reactions in a one-pot way. This review therefore aims to provide a comprehensive account of the most significant advances in the development of functionalised heterogeneous catalysts for efficient biomass upgrading. In addition, this review highlights important progress ensued in tailoring the immobilisation of desirable functional groups on particular sites of the above-listed materials, while critically discussing the role of consequent properties on cascade reactions as well as on other vital processes within the bio-refinery. Current challenges and future opportunities towards a rational design of novel functionalised heterogeneous catalysts for sustainable biomass valorisation are also emphasized.

“…For example, Wang and co‐workers developed a surface‐energy–driven approach by using PVP to synthesize a series of well‐defined hollow MOF (e.g., MOF‐5, MOF‐5(FeII), and MOF‐5(FeIII)) nanocages. [10b] Wu and co‐workers further followed Wang’s method to encapsulate phosphotungstic acid inside MOFs . Lei and co‐workers synthesized hollow ZIF‐8 structures with the assistance of sodium dodecyl sulfate …”

“…[10b] They found that such hollow structures had better activity than PdCu dendrites, because the hydrogenation reaction was accelerated in the hollow nanoreactors. Analogously, hollow phosphotungstic acid (PTA)@CdCu@MOF‐5(FeIII) yolk–shell nanostructures showed good selective hydrogenation performance toward palmitic acid . Except for the activity, the MOFs nanoreactors exhibit a considerable effect on the catalytic selectivity.…”

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.

“…Advances in Polymer Technology e presence of oxygen-containing C16-C18 fatty acids causes polymerization, weak oxidation stability, and low calorific value, even when cannot efficiently utilize the algaederived bio-oil for transportation fuel. Considering this, Fang et al [69] researched the facile conversion of palmitic acid to hexadecane catalyzed by the bifunctional PTA@ PdCu@Fe III -MOF-5, which was prepared by immobilizing phosphotungstic acid into the MOF structure. e explored catalyst demonstrates an enhanced acidity and efficiently facilitates palmitic acid for hexadecane with relatively high selectivity.…”

Currently, pristine and functionalized metal-organic frameworks (MOFs) are introduced in heterogeneous catalysis for biomass upgrading owing to the specific texture properties including regular higher-order structure, high specific surface area, and the precisely tailored diversity. The purpose of this review is to afford a comprehensive discussion of the most applications in biomass refinery. We highlight recently developed four types of MOFs like pristine MOFs and their composites, MOF-supported metal NPs, acid-functionalized MOFs, and biofunctionalized MOFs for production of green, sustainable, and industrially acceptable biomass-derived platform molecules: (1) upgrading of saccharides, (2) upgrading of furan derivatives, and (3) upgrading of other biobased compounds.

Upgrading of palmitic acid over MOF catalysts in supercritical fluid of n-hexane

Abstract: The addition of phosphotungstic acid (PTA) to the synthesis mixture of PdCu@FeIII–MOF-5 yields the direct encapsulation of PTA inside the MOF structure (i.e. PTA@PdCu@FeIII–MOF-5) through a facile solvothermal approach.
