Nanostructured materials, such as zeolites and metal-organic frameworks, have been considered to capture CO2. However, their application has been limited largely because they exhibit poor selectivity for flue gases and low capture capacity under low pressures. We perform a high-throughput screening for selective CO2 capture from flue gases by using first principles thermodynamics. We find that ...
Abstract The increasing emission of carbon dioxide (CO 2 ) to the atmosphere has gained worldwide concern due its main contribution climate changes, global warming, and greenhouse effect. Numbers technologies have been carried out remove this hazardous gas from environment such as absorption, adsorption, membrane separation, cryogenic biological process. Due limitation current absorption techni...
Environmental pollutions especially water pollution has been a persisting issue battle by mankind worldwide. There are various kinds of pollutants in contaminated where it varies from heavy metals, organic dyes, pharmaceutical products and others. The presence all these poses adverse effect to both animal human as most them toxic. With the depleting sources clean water, needs treatment for poll...
We report iron-containing mixed-oxide nanocomposites as highly effective redox materials for thermochemical CO2 splitting and methane partial oxidation in a cyclic redox scheme, where methane was introduced as an oxygen "sink" to promote the reduction of the redox materials followed by reoxidation through CO2 splitting. Up to 96% syngas selectivity in the methane partial oxidation step and clos...
