Emulsion templating presently extends far beyond the original hydrophobic porous polymers that were synthesized within surfactant-stabilized water-in-oil high internal phase emulsions (HIPEs) by using free radical polymerization. This Perspective presents the extraordinary versatility of emulsion templating that has emerged with the growing numbers of HIPE systems, HIPE stabilization strategies, monomers, polymerization chemistries, multicomponent materials, and surface functionalities. Emulsion templating now goes far beyond "porous polymers" by encompassing the encapsulation of aqueous solutions, ionic melts, and organic liquids as well as by encompassing porous carbons and porous inorganics. Herein, we present comprehensive pictures of the state-of-the-art, of the prospective large-scale and niche applications, of the advantages and challenges for industrial scale-up, and of the crucial directions that should be pursued in future work. We demonstrate that it is emulsion templating's considerable and versatile parameter space that offers opportunities for pioneering work, breakthrough innovations, scientific/engineering achievements, and industrial adoption.

“…Hf-based MOFs have been attracting attention owing to their high crystallinity Hf-based MOFs can be obtained rapidly in large quantities by selecting conditioner and reaction conditions. − Today, Hf-based MOFs have been broadly adopted in gas storage/separation, biomedical therapy, and other fields due to their structural diversity and excellent structural stability. − However, the studies related to proton conduction were late, − which motivated us to carry out studies related to proton conduction in Hf-based MOFs. In our previous work, we selected a rapid synthesis method to synthesize two Hf(IV)-based compounds: Hf-UiO-66-(OH) 2 ( 1 ) and Hf-UiO-66-NH 2 ( 2 ) .…”

Recently, researchers have focused on preparing and studying proton exchange membranes. Metal−organic frameworks (MOFs) are candidates for composite membrane fillers due to their high crystallinity and structural characteristics, and Hf-based MOFs have attracted our attention with their high porosity and high stability. Therefore, in this study, Hf-based MOFs were doped into a costeffective chitosan matrix as fillers to fabricate composite films having excellent proton conductivity (σ). First, the nanoscale MOFs Hf-UiO-66-(OH) 2 (1) and Hf-UiO-66-NH 2 (2) were chemically modified by a ligand design strategy to obtain SA-1 and CBD-2 bearing free −COOH units. The proton conductivities of SA-1 and CBD-2 under optimal test conditions reached 1.23 × 10 −2 and 0.71 × 10 −2 S cm −1 . After that, we prepared composite membranes CS/SA-1 and CS/ CBD-2 by the casting method; tests revealed that the introduction of MOFs improved the stabilities and σ values of the membranes, and their best σ could reach above 10 −2 S cm −1 under 100 °C/98% RH. Further structural characterization and activation energy calculation revealed the conductive mechanism of the composite films. This investigation not only proposes a novel chemical modification method for optimizing the σ of MOFs but also promotes the development of MOF-doped composite membranes and provides a basis for future applications of MOFs in fuel cells.

“…UiO-66 stands as a representative MOF, a Zr-based catalyst containing benzene-1,4-dicarboxylate (BDC) linkers, demonstrating high structural thermal stability (up to 500 °C). [77][78] According to Zhao et al, [79] the combination of UiO-66À NH 2 and sulfonated Poly-Pickering HIPEs (PHsÀ SO 2 H) in the appropriate weight ratio was more effective in converting cellulose to HMF in [BMIM]Cl media than using UiO-66À NH 2 or PHsÀ SO 2 H alone. The macroporous structure of PHsÀ SO 3 H, along with its sulfonic acid group, provided efficient active sites for cellulose catalysis and reduced diffusion resistance, leading to an increased reaction rate.…”

The catalytic conversion of lignocellulose‐derived carbohydrates, particularly cellulose, into 5‐hydroxymethylfurfural (HMF), holds significant potential as a crucial step in the sustainable production of valuable platform chemicals. This review presents the remarkable progress made in the field, with a specific emphasis on the role of heterogeneous catalysts, innovative methods for accelerating cellulose hydrolysis, and the design of flow reactor technologies. The distinctive properties and surface functionalities of catalysts facilitate the efficient breakdown of cellulose's intricate structure, thereby promoting selective hydrolysis leading to HMF formation. Therefore, this review comprehensively examines various categories of heterogeneous catalysts, including metal oxides/phosphates, zeolites, functionalized silica/carbon‐based materials, heteropolyacids (HPAs), and metal‐organic frameworks (MOFs), highlighting their unique mechanisms and performance in cellulose conversion. Furthermore, the review describes the intriguing progress in hydrolysis strategies (pretreatment techniques and advanced heating systems) that have been crucially involved in overcoming the challenges associated with cellulose recalcitrance and achieving enhanced HMF yields. The synergistic interactions between catalysts and innovative hydrolysis methods have played a central role in the breakthroughs within cellulose conversion technology. Another aspect covered in this work is the advancement in using fixed‐/fluidized‐bed reactors and slug microreactors for the continuous production of HMF. Lastly, the current challenges and future perspectives are presented to propose the dilemma and development direction for efficient cellulose‐to‐HMF conversion.
