A review of the features and applications of ZIF-8 and its derivatives for separating CO2 and isomers of C3- and C4- hydrocarbons
Bergaoui, Manel; Khalfaoui, Mohamed; Awadallah-F, Ahmed; Al-Muhtaseb, Shaheen ( Elsevier , 2021 , Article Review)Metal organic framework (MOF) membranes have gained more attentions due to their abilities in various applications in gas and liquid separations. The majority of works are related to Zeolite imidazolate frameworks-8 (ZIF-8). ... -
Carbon dioxide sequestration and methane removal from exhaust gases using resorcinol-formaldehyde activated carbon xerogel
Awadallah-F, Ahmed; Al-Muhtaseb, Shaheen A. ( Springer , 2013 , Article)The world is faced with intrinsic environmental issues. Among these issues, the minimization of greenhouse gas emission to acceptable levels presents a high priority. This study seeks to help to reduce the greenhouse effect ... -
Carbon Nanoparticles-Decorated Carbon Nanotubes
Awadallah-F, Ahmed; Al-Muhtaseb, Shaheen ( Nature Research , 2020 , Article)© 2020, The Author(s). Multi walled carbon nanotubes (MWCNTs) were decorated by activated carbon nanoparticles of resorcinol-formaldehyde aerogels. Carbon nanospheres and MWCNTs were mixed by equal mass ratios for different ... -
Impact of synthesis conditions on meso- and macropore structures of resorcinol-formaldehyde xerogels
Awadallah-F, Ahmed; Elkhatat, Ahmed M.; Al-Muhtaseb, Shaheen A. ( Springer , 2011 , Article)Xerogels were prepared by the sol-gel polymerization of resorcinol with formaldehyde at different conditions. The effects of different synthesis factors (namely, resorcinol-to-formaldehyde ratio, resorcinol-to-water ratio, ... -
Influence of carbon uniformity on its characteristics and adsorption capacities of CO2 and CH4 gases
Awadallah-F, Ahmed; Al-Muhtaseb, Shaheen A. ( MDPI AG , 2021 , Article)Activated carbons of resorcinol-formaldehyde aerogels (AC-RFA) were prepared and mixed with multiwall carbon nanotubes (MWCNTs) with various ratios. Samples were characterized by different techniques. The novelty of the ... -
Influence of micro-and mesoporosity of resorcinol-formaldehyde xerogels on adsorption
Awadallah-F, Ahmed; Al-Muhtaseb, Shaheen A. ( Mary Ann Liebert , 2013 , Article)Effects of micro-and mesoporosity of resorcinol-formaldehyde xerogels (RFXs) on the adsorptive properties of crystal violet (CV) were investigated. RFXs were synthesized at different pH values, and corresponding pore ... -
