Design of Amine-Containing Nanoporous Materials for Postcombustion CO Capture from Engineering Perspectives.

ConspectusCarbon dioxide (CO) capture and storage (CCS) is a means to enable the continued use of fossil fuels in the short term. In particular, postcombustion CO capture has attracted considerable attention because it can be retrofitted into existing power plants and industrial plants. Among various CO capture technologies, the absorption of CO using aqueous amines has been industrially employed for decades.

First successful synthesis of an Al-rich mesoporous aluminosilicate for fast radioactive strontium capture.

Al-rich zeolites such as NaA (Si/Al = 1.00) have been widely applied to remove radioactive Sr because of their high surface charge density enabling efficient ion-exchange of multivalent cations. However, due to the small micropore diameters of zeolites and large molecular size of strongly hydrated Sr, Sr-exchange with zeolites suffers from very slow kinetics.
