Oxygen enriched network-type carbon spheres for multipurpose water purification applications

Sami Rtimi

Potassium hydroxide (KOH) modified network-type carbon spheres (CSs) with abundant oxygen-rich groups were synthesized using a simple hydrothermal carbonization (HTC) of glucose precursor and utilized for the adsorptive removal of cadmium(II) heavy metal a ...

Some nanoporous, crystalline materials possess dynamic constituents, for example, rotatable moieties. These moieties can undergo a conformation change in response to the adsorption of guest molecules, which qualitatively impacts adsorption behavior. We pos ...

National Academy of Sciences2017

The removal of sulfur compounds in biomass gasification processes is crucial to protect downstream equipment. While conventional sorbent materials can retain H2S, many fail to capture heterocyclic sulfur compounds such as thiophene (C4H4S). This work explo ...

Activated carbon fibers for efficient VOC removal from diluted streams: the role of surface functionalities

Lioubov Kiwi, Guillaume Bastien Baur, Oliver Anthony Beswick, Jonathan Spring

The effect of surface functionalities, specific surface area and pore size of activated carbon fibers (ACFs) on the adsorption of toluene and acetaldehyde, two volatile organic compounds (VOC), at low concentrations (similar to 80 ppmv) and short contact t ...

Springer2015

Contamination of the environment by anthropogenic volatile organic compounds (VOC) became of major concern during the last decades. Present in gas streams of many industrial exhausts, they are harmful and detrimental for both human health and environment e ...

Activated carbon fibers modified by metal oxide as effective structured adsorbents for acetaldehyde

Lioubov Kiwi, Guillaume Bastien Baur

Novel efficient adsorbents for acetaldehyde removal from diluted gas streams (similar to 1300 ppmv) have been developed. The adsorbents combine the properties of activated carbon fibers (ACF) and nanoparticles (NPs) of basic metal oxides (La2O3, CaO, MgO, ...

Gas separations in metal-organic frameworks

Wendy Lee Queen, Miguel Gonzalez

Owing to their high surface areas, tunable pore dimensions, and adjustable surface functionality, metal-org. frameworks (MOFs) can offer advantages for a variety of gas storage and gas sepn. applications. In an effort to help curb greenhouse gas emissions ...

Flexible metal-organic framework compounds: In situ studies for selective CO2 capture

Wendy Lee Queen

Results are presented that explore the dynamic structural changes occurring in two highly flexible nanocryst. metal-org. framework (MOF) compds. during the adsorption and desorption of pure gases and binary mixts. The Ni(1,2-bis(4-pyridyl)ethylene)[Ni(CN)4 ...
