Solid State NMR for Mechanistic Exploration of CO Adsorption on Amine-Based Silica Adsorbents.

Mitigating atmospheric carbon dioxide concentrations is crucial because elevated CO levels drive climate change by enhancing the greenhouse effect, leading to global warming, extreme weather events, ocean acidification, loss of biodiversity, and significant socioeconomic and health challenges for ecosystems and human populations. The necessity to reduce atmospheric carbon dioxide levels has led to the creation of novel materials designed to effectively capture and convert CO using carbon capture and utilization methods. A diverse array of materials such as metal-organic frameworks, covalent organic frameworks, porous carbon, zeolites, and amine functionalized silica has been reported for efficient carbon dioxide capture.
