“…Increased research focus on Zr-based MOFs is apparent as a result of their significant thermal and chemical stability [88], a property which can be attributed to strong coordination interactions of high charge density zirconium (Zr(IV)) ions with oxygen component of organic linkers. A microwave-assisted solvothermal approach to prepare phase pure MIL-140 was described by Liang et al in 2013 [89], resulting in a superior compound with reduced preparation time than that required for conventional electric heating approaches. The generation of highly crystalline, prototype, octahedral-shaped crystals of UiO-66 with 1.26 wt.% H 2 storage capacity was developed by Ren et al using a process which required as little as 5 min to complete [90].…”

Increasing number of metal-organic frameworks (MOFs) have recently been recognised as a new generation of emerging porous photocatalysts in photocatalysis and photoelectrocatalysis, since their intrinsic coordination structure between the metal cluster and organic ligands offers MOFs great flexibility to tune their semiconducting property for enhanced light harvesting. In order to improve their performance substantially and achieve widespread application of MOF photocatalysts, it is necessary to develop effective synthesis strategies and understand their semiconducting crystal structure, photocatalytic mechanism in depth. This chapter firstly provides a brief introduction of the MOF materials; this chapter addresses the crystallinity, porosity and electronic semiconducting structures that are essential in solar energy conversion. Established and innovative syntheses strategies of MOFs are then categorised and illustrated, followed by various characterisations techniques applied to investigate their structural and semiconducting properties (band structure and charge transfer), including X-ray Diffraction XRD, small angle X-ray Diffraction SAXRD, adsorption/desorption, UV-Vis, nuclear magnetic resonance (NMR), extended fine Auger structures (EXFAS), inelastic neutron scattering (INS) spectroscopy, high-resolution transmission electron microscopy (HR)TEM and electrochemical measurements. The photocatalytic and photoelectrocatalytic application of MOFs are introduced addressing their unique photocatalytic mechanism. The perspectives of MOF photocatalysts are finally presented to encourage the future development. The content of this chapter suits the users including beginners, postgraduates and professionals.

“…[74] Soon after, in the presence of formic acid modulator, UiO-66 was also successfully synthesized in just 5 minutes. [75] The synthesized UiO-66 is comparable to those prepared from long-time conventional method in the aspect of specific surface area, crystal size, and hydrogen storage capacity, suggesting that the rapid reaction had no obvious side-effect on the nucleation and intrinsic properties of this ZrÀ MOF. In the following research, there is a growing interest about how to achieve a greater production capacity of prototype ZrÀ MOF.…”

“…In recent years, the relationship between MIL‐140 and UiO‐66’s structures and the mechanisms affecting their formation have been systematically explored, and many works were based on the efficiency and phase‐selectivity of the microwave‐assisted method [74] . Soon after, in the presence of formic acid modulator, UiO‐66 was also successfully synthesized in just 5 minutes [75] . The synthesized UiO‐66 is comparable to those prepared from long‐time conventional method in the aspect of specific surface area, crystal size, and hydrogen storage capacity, suggesting that the rapid reaction had no obvious side‐effect on the nucleation and intrinsic properties of this Zr−MOF.…”

Zirconium‐based metal‐organic framework materials (Zr−MOFs) have more practical usage over most conventional benchmark porous materials and even many other MOFs due to the excellent structural stability, rich coordination forms, and various active sites. However, their mass‐production and application are restricted by the high‐cost raw materials, complex synthesis procedures, harsh reaction conditions, and unexpected environmental impact. Based on the principles of “Green Chemistry”, considerable efforts have been done for breaking through the limitations, and significant progress has been made in the sustainable synthesis of Zr−MOFs over the past decade. In this review, the advancements of green raw materials and green synthesis methods in the synthesis of Zr−MOFs are reviewed, along with the corresponding drawbacks. The challenges and prospects are discussed and outlooked, expecting to provide guidance for the acceleration of the industrialization and commercialization of Zr−MOFs.

Usually, porous materials are synthesized by using conventional electric heating, which can be energy‐ and time‐consuming. Microwave heating is commonly used in many households to quickly heat food. Microwave ovens can also be used as powerful devices in the synthesis of various porous materials. The microwave‐assisted synthesis offers a simple, fast, efficient, and economic way to obtain many of the advanced nanomaterials. This review summarizes the recent achievements in the microwave‐assisted synthesis of diverse groups of nanoporous materials including silicas, carbons, metal–organic frameworks, and metal oxides. Microwave‐assisted methods afford highly porous materials with high specific surface areas (SSAs), e.g., activated carbons with SSA ≈3100 m2 g−1, metal–organic frameworks with SSA ≈4200 m2 g−1, covalent organic frameworks with SSA ≈2900 m2 g−1, and metal oxides with relatively small SSA ≈300 m2 g−1. These methods are also successfully implemented for the preparation of ordered mesoporous silicas and carbons as well as spherically shaped nanomaterials. Most of the nanoporous materials obtained under microwave irradiation show potential applications in gas adsorption, water treatment, catalysis, energy storage, and drug delivery, among others.
