An amine phase-transfer approach is a novel design
for the facile and recyclable fixation and nonbiological mineralization
of CO2 into alkaline earth carbonate (MCO3,
M = Ca, Sr, and Ba) crystals with uniformed polymorphs at room temperature
under atmospheric pressure. The amines’ system based on two
phases of water and Zn-tetraphenylporphyrin (ZnTPP) in CH2Cl2 provides a green and sustainable CO2 capture
and utilization (CCU) strategy for the mitigation of anthropogenic
CO2 emission to the atmosphere.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
