The presence of hexavalent chromium water pollution is a growing global concern. Among the currently applied technologies to remove CrVI, its adsorption and photocatalytic reduction CrIII less mobile toxic forms are most appealing because their simplicity, reusability, low energy consumption. However, little attention has been paid bifunctional catalysts, that is, materials can reduce CrVI reta...

Separation of CO2 involving mixtures is relevant to the various industrial settings and preserving environment for which different classes materials including metal-organic frameworks (MOFs) have been researched. Herein, CO2/CO, CO2/H2, CO2/N2, H2S/CO2 separation properties zirconium MOFs are computationally investigated mimicking vacuum swing adsorption (VSA) process. Structure-performance rel...

Ultrawideline dynamic nuclear polarization (DNP)-enhanced (195)Pt solid-state NMR (SSNMR) spectroscopy and theoretical calculations are used to determine the coordination of atomic Pt species supported within the pores of metal-organic frameworks (MOFs). The (195)Pt SSNMR spectra, with breadths reaching 10 000 ppm, were obtained by combining DNP with broadbanded cross-polarization and CPMG acqu...

Knowing that the world is facing a shortage of fresh water, desalination, in its different forms including reverse osmosis, represents a practical approach to produce potable water from a saline source. In this report, two kinds of Metal-Organic Frameworks (MOFs) nanoparticles (NPs), UiO-66 (~100 nm) and MIL-125 (~100 nm), were embedded separately into thin-film composite membranes in different...

We report on a concept of co-pelletization using mechanically robust hydroxylated UiO-66 to develop metal-organic framework (MOF) monolith that contains 5 wt% electrospun polymer nanofibers, and consists an architecture with alternating layers MOF nanofiber mats. The polymers choice were the microporous Polymer Intrinsic Microporosity (PIM-1) non-porous polyacrylonitrile (PAN). Co-pelletized Ui...

Rutherford backscattering spectrometry (RBS) has been used for the first time to study post-synthetic linker exchange (PSE) in metal-organic frameworks. RBS is a non-invasive method to quantify the amount of introduced linker, as well as providing a means for depth profiling in order to identify the preferred localization of the introduced linker. The exchange of benzenedicarboxylate (bdc) by s...
