Halogen-Decorated Metal-Organic Frameworks for Efficient and Selective CO Capture, Separation, and Chemical Fixation with Epoxides under Mild Conditions.

In the present work, three novel halogen-appended cadmium(II) metal-organic frameworks [Cd(L1)(4,4'-Bipy)]·4(DMF) (), [Cd(L2)(4,4'-Bipy)]·3(DMF) (), and [Cd(L3)(4,4'-Bipy)]·2(DMF) () [where L1 = 5-{(4-bromobenzyl)amino}isophthalate; L2 = 5-{(4-chlorobenzyl)amino}isophthalate; L3 = 5-{(4-fluorobenzyl)amino}isophthalate; 4,4'-Bipy = 4,4'-bipyridine; and DMF = ,'-dimethylformamide] have been synthesized under solvothermal conditions and characterized by various analytical techniques. The single-crystal X-ray diffraction analysis demonstrated that all the MOFs feature a similar type of three-dimensional structure having a binuclear [Cd(COO)(N)] secondary building block unit. Moreover, MOFs and contain one-dimensional channels along the -axis, whereas MOF possesses a 1D channel along the -axis.

Novel Carbonaceous Adsorbents Prepared from Glycerin Waste and Dopamine for Gas Separation.

Glycerin, a low-valued waste from biodiesel production, and dopamine were used as precursors for adsorbent materials. The study is centered on the preparation and application of microporous activated carbon as adsorbent materials in the separation of ethane/ethylene and of gases that are natural gas or landfill gas components (ethane/methane and carbon dioxide/methane). The activated carbons were produced by the following sequence reactions: facile carbonization of a glycerin/dopamine mixture and chemical activation.

Dataset for the synthesis, characterisation and application of cobalt and nitrogen co-doped TiO nanoparticles on triclosan photodegradation using visible LED light.

The growing threat of emerging waterborne contaminants is a global concern, fuelled in part by the ineffectiveness of current remediation strategies. One of the most prominent remediation strategies is catalytic photodegradation, particularly with TiO nanoparticles (NPs), but its full utilization is hampered by using only UV radiation, which is scarce in sunlight. To fully benefit from the sunlight abundance, several efforts are focused on the tailoring of TiO to make it more active in visible (Vis) light.

Chitosan Biocomposites for the Adsorption and Release of HS.

The search for HS donors has been increasing due to the multiple therapeutic effects of the gas. However, the use of nanoporous materials has not been investigated despite their potential. Zeolites and activated carbons are known as good gas adsorbents and their modification with chitosan may increase the material biocompatibility and simultaneously its release time in aqueous solution, thus making them good HS donors.
