Nanoporous graphene membranes have drawn special attention in the gas-separation processes due to their unique structure and properties. The complexity of physical understanding such membrane designs restricts widespread use for applications. In present study, we strive propose promising face this technical challenge. regard, investigated permeation separation mixture adsorptive gases CO2 CH4 t...

the process environment are needed in many emerging energy and environment technologies, ranging from membranes for gas separation (e.g., carbon capture), water purification (e.g., desalination), to clean energy production (e.g., fuel cell). In the Guo group at the University of Notre Dame, we are focused on molecularly engineering polymer and polymer-based membranes that are both structurally ...

Graphdiyne, a recently synthesized one-atom-thick carbon allotrope, is atomistically porous - characterized by a regular "nanomesh"- and suggests application as a separation membrane for hydrogen purification. Here we report a full atomistic reactive molecular dynamics investigation to determine the selective diffusion properties of hydrogen (H(2)) amongst carbon monoxide (CO) and methane (CH(4...

Growing evidence indicates that the CO2 emissions from the combustion of fossil fuels are contributing to global climate change. One indispensable approach to controlling CO2 emissions to the atmosphere is carbon capture, utilization and sequestration (CCUS) from large point sources, such as coal power plants. Membrane technology has emerged as an important separation technology for CO2 capture...
