“…Yang et al also employed EB-COF:Br on the adsorption of the excess phosphorous acid at extremely acid conditions (pH = 0.86-0.65) with high maximum adsorption capacity ranging from 6520 to 6980 mg g −1 at 25-45 °C (Yang et al 2020b). The sulfonated COF (SO 3 H@COF) also showed satisfactory results toward adsorption of Cd 2+ , Co 2+ , and Cr 3+ heavy metal ions, revealing high maximum adsorption capacity at 298 K of 81.97, 77.52, and 105.26 mg g −1 , respectively (Wang et al 2020a, b).…”

“…As a comparison, the NG of the reactants showed only H2BDC ligand peaks in PXRD with no trace of MOF-5 (Prochowicz et al 2015). A series of MOF-74 families have been successfully synthesized via mechanochemical method using Hünig's base (N, N´-diisopropylethylamine) as both the liquid for LAG and the base required to facilitate MOFs formation, resulting in a high-quality MOF-74 in a scalable and sustainable manner (Wang et al 2020a;.…”

Ordered nanoporous materials have attracted much attention due to their unique pore architecture, tunable physicochemical properties, which find applications in a broad spectrum of catalysis, separation, adsorption, drug delivery, energy storage, and sensing. In the past decades, the amount of research on ordered nanoporous materials has grown incrementally, resulting in diverse types of these materials with unprecedented structures. Herein, this chapter presents the recent advances of ordered nanoporous materials, including zeolites, ordered mesoporous materials (OMMs), metal-organic frameworks (MOFs), and covalent organic frameworks (COFs). Several vital aspects, i.e., structural and physicochemical properties,

“…They have atomically precise porous structures and can have excellent chemical stability in organic solvents, resisting adverse conditions such as acidic and basic conditions to maintain orderly structures and crystallinity [127,128]. In addition, their high stability results from the purely covalent bond and metal-free structures [127,129]. Due to their excellent properties, such as high thermal and chemical stability, large surface area, excellent pore properties, traceable physical and chemical properties, and ease of operation, COFs exhibit excellent performance in the areas of gas storage and separation, analytical chemistry, catalysis, electrical and storage devices, optoelectronics and drug detection [130][131][132][133].…”

The market for industrial enzymes has witnessed constant growth, which is currently around 7% a year, projected to reach $10.5 billion in 2024. Lipases are hydrolase enzymes naturally responsible for triglyceride hydrolysis. They are the most expansively used industrial biocatalysts, with wide application in a broad range of industries. However, these biocatalytic processes are usually limited by the low stability of the enzyme, the half-life time, and the processes required to solve these problems are complex and lack application feasibility at the industrial scale. Emerging technologies create new materials for enzyme carriers and sophisticate the well-known immobilization principles to produce more robust, eco-friendlier, and cheaper biocatalysts. Therefore, this review discusses the trending studies and industrial applications of the materials and protocols for lipase immobilization, analyzing their advantages and disadvantages. Finally, it summarizes the current challenges and potential alternatives for lipases at the industrial level.

Covalent Organic Frameworks: Synthesis, Properties and Applications—An Overview

Covalent Organic Frameworks (COFs) are an exciting new class of microporous polymers with unprecedented properties in organic material chemistry. They are generally built from rigid, geometrically defined organic building blocks resulting in robust, covalently bonded crystalline networks that extend in two or three dimensions. By strategically combining monomers with specific structures and properties, synthesized COF materials can be fine-tuned and controlled at the atomic level, with unparalleled precision on intrapore chemical environment; moreover, the unusually high pore accessibility allows for easy post-synthetic pore wall modification after the COF is synthesized. Overall, COFs combine high, permanent porosity and surface area with high thermal and chemical stability, crystallinity and customizability, making them ideal candidates for a myriad of promising new solutions in a vast number of scientific fields, with widely varying applications such as gas adsorption and storage, pollutant removal, degradation and separation, advanced filtration, heterogeneous catalysis, chemical sensing, biomedical applications, energy storage and production and a vast array of optoelectronic solutions. This review attempts to give a brief insight on COF history, the overall strategies and techniques for rational COF synthesis and post-synthetic functionalization, as well as a glance at the exponentially growing field of COF research, summarizing their main properties and introducing the numerous technological and industrial state of the art applications, with noteworthy examples found in the literature.
