研究目的
Investigating the adsorption of CO2 on amine-modified silica studied by infrared spectroscopy.
研究成果
IR spectroscopy has been instrumental in revealing the CO2–amine chemistry on silica supports, showing that ammonium-carbamate ion pairs are preferred at high amine densities, while carbamic acid and related moieties form at lower densities. The study also highlights the degradation of amines under cyclic thermal treatment and suggests further research into the formation of bicarbonates, the use of alternative supports, and the detailed study of amine degradation products.
研究不足
The study is limited to the use of silica as the primary support for amines, with suggestions for future research to include other supports. The formation of bicarbonates under humid conditions and the degradation products of amines under thermal cycling are areas identified for further investigation.
