“…As is well-known, the pseudo-first-order kinetic model is efficiently used for photocatalytic degradations. 15 Consequently, the slopes of the fitting straight lines based on the graph of –ln( C / C 0 ) vs. time, 41 seen in eqn (2), correspond to their first-order rate constants.…”

“…This acid tends to interact with ˙OH radicals to generate 2-hydroxyterephthalic acid at an excitation wavelength of 300 nm. 15 Measuring the concentration of formed 2-hydroxyterephthalic acid could quantify the ˙OH radicals in the samples. The spin-trapping electron paramagnetic resonance (EPR) spectra were collected 30 s after the introduction of the respective photocatalysts via an X-band EPR spectrometer (MS 5000, Magnetek, Germany).…”

Metal Organic Frameworks (MOFs) are expected to become a major player in different industrial sector as a result of biological performance, photocatalysis, adsorption and absorption behavior, capacitance, improved anodic performance in energy storage. In biomedical industries, MOFs utilize antimicrobial characteristics and biosensing, bioimaging, therapeutic, drug delivery capabilities. MOF can be used as a food safety and food packaging agent since they prevent microbes. By photocatalysis MOF can contribute to wastewater treatment. MOFs adsorption and absorption characteristics can remediate groundwater. Improved capacitance and anodic behavior of MOF will contribute to energy storage device improvement. MOFs are also capable of separating gases from mixtures. Thus, MOF will play vital role in biomedical, food, water-treatment industry, oil-gas industry, and energy storage industry. Energy, environment, biomedical applications make MOF important in 4 th industrial revolution. This study will focus on special properties along with different industrial application and show the effectiveness of MOF in 4 th industrial application.

“…ZIFs have gained technical and scientific attention due to their pore-structural network, and have many potential applications in the fields of photocatalysis [103], drug delivery [104], pharmaceutical compounds separation [105,106], dye-wasted water treatment [107], oil-water separation [108], water purification [109,110], the pervaporation recovery of solvent vapors [109,[111][112][113], electrocatalysts [114], solvent-resistant nanofiltration [115], gas-liquid separation [116], natural gas separation [117][118][119] and so on. As described in Figure 2, MMMs may provide separation properties that can overcome the Robeson upper bound.…”

Since the second industrial revolution, the use of fossil fuels has been powering the advance of human society. However, the surge in carbon dioxide (CO2) emissions has raised unsettling concerns about global warming and its consequences. Membrane separation technologies have emerged as one of the major carbon reduction approaches because they are less energy-intensive and more environmentally friendly compared to other separation techniques. Compared to pure polymeric membranes, mixed matrix membranes (MMMs) that encompass both a polymeric matrix and molecular sieving fillers have received tremendous attention, as they have the potential to combine the advantages of both polymers and molecular sieves, while cancelling out each other’s drawbacks. In this review, we will discuss recent advances in the development of MMMs for CO2 separation. We will discuss general mechanisms of CO2 separation in an MMM, and then compare the performances of MMMs that are based on zeolite, MOF, metal oxide nanoparticles and nanocarbons, with an emphasis on the materials’ preparation methods and their chemistries. As the field is advancing fast, we will particularly focus on examples from the last 5 years, in order to provide the most up-to-date overview in this area.
