Titanium enhanced carbon capture of lithium orthosilicate in a binary lithium source

Herein, we reported a synergistic strategy using a binary Li₂CO₃/LiOH lithium source coupled with TiO₂ incorporation to enhance the CO₂ capture performance of Li₄SiO₄. The mixed lithium precursor improved CO₂ capture capacity, while TiO₂ incorporation further stabilized its structure to suppress sintering over long cycles. Our work thus provided an effective strategy for developing high-performance oxide-based sorbents for CO₂ capture.
