Nanocomposite Membrane Containing Bio-nanofibers and Mimic Enzyme for CO2 Separation

Although there has been growing concern about climate change over the last decade, the concentration of carbon dioxide in the atmosphere has surpassed the milestone level of 400 parts per million (ppm) for the first time in human history in May 2013. More effective technologies are required for CO2 capture from various energy related sources. Currently, amine-based absorption is the leading technology for CO2 separation. However, amine absorption has a potential of pollution, and is costly and energy intensive. It is therefore urgent to develop green technologies that can reduce pollution and also be economically competitive compared to the amine absorption process.

NanoMBE focuses on developing nanocomposite membranes that can significantly increase the separation performance of gas separation membranes.

The project aims to improve membrane separation efficiency of power plant flue gas (CO2/N2 separation) and to upgrade biogas (CO2/CH4 separation).

This project is based on highly interdisciplinary knowledge, including nano-technology, membrane technology, bio-technology and material chemistry.
