Thermal conversion of a tailored metal-organic framework into lithium silicate with an unusual morphology for efficient CO2 capture.

The conversion reaction of metal-organic frameworks (MOFs) was adopted as a synthetic method to produce an advanced CO2 absorbent. A Li- and Si-containing MOF is a good precursor for lithium orthosilicate (Li4SiO4); the resulting solid has an unusual coral-like morphology, which provides an enhanced CO2-sorption performance (high uptake and fast absorption).
