Preparation and CO2 separation properties of amine-modified mesoporous silica membranes

Synthesis and characterization of organoamine-functionalized amorphous silica materials for CO₂-selective membranes

“…Typical literature methods of alkylamino-group functionalized silica-based materials have been reported, namely the acid-catalyzed solgel method, 9) as well as the surface modification of mesoporous silica materials. 1) These techniques however are not suitable for the fabrication of CO 2 separation materials, because of the acidic catalysis that leads to the undesired ammonium salt formation, thus preventing the amine function from capturing CO 2 . Therefore, the possibility to obtain organoamine-functionalized silica by in situ conversion of inorganic precursors is a promising route in order to overcome this major limitation.…”

“…1) As mentioned in the United Nations historic Framework for Disaster Risk Reduction 2015 2030 adopted at the 3rd World Conference on Disaster Risk Reduction (WCDRR) in Sendai: addressing climate change as one of the drivers of disaster risk, while respecting the mandate of the United Nations Framework Convention on Climate Change, represents an opportunity to reduce disaster risk in a meaningful and coherent manner.…”

Morphology Control of Ordered Mesoporous Carbon Using Organic-Templating Approach

“…FESEM image for the cross-section of CKU-F69. (Tanaka et al, 2007) Microporous and mesoporous inorganic membranes have been investigated mainly with respect to silica membrane prepared by the sol-gel method (Park et al, 2001;Nishiyama et al, 2003;Sakamoto et al, 2007). However, silicate materials dissolved in water and alkaline solutions, which decrease the possibility of practical use.…”

Polymer-derived organoamine-functionalized amorphous silica materials for CO₂ capture

“…1) The Paris Agreement which has been adopted at the 21st session of the Conference of the Parties (COP21) to the United Nations Framework Convention on Climate Change (UNFCCC) emphasizes the need for urgency in addressing climate change, as it represents a potentially irreversible threat to human societies and the planet. An appropriate and effective international response requires the widest possible cooperation by all countries, with a view to accelerating the reduction of global greenhouse gas emissions and holding the increase in the global average temperature to well below 2°C above preindustrial levels, and pursuing efforts to limit the temperature increase to 1.5°C.…”
