Performance of Li(4)SiO(4) Material for CO(2) Capture: A Review

Lithium silicate (Li(4)SiO(4)) material can be applied for CO(2) capture in energy production processes, such as hydrogen plants, based on sorption-enhanced reforming and fossil fuel-fired power plants, which has attracted research interests of many researchers. However, CO(2) absorption performance of Li(4)SiO(4) material prepared by the traditional solid-state reaction method is unsatisfactory during the absorption/regeneration cycles. Improving CO(2) absorption capacity and cyclic stability of Li(4)SiO(4) material is a research highlight during the energy production processes. The state-of-the-art kinetic and quantum mechanical studies on the preparation and CO(2) absorption process of Li(4)SiO(4) material are summarized, and the recent studies on the effects of preparation methods, dopants, and operating conditions on CO(2) absorption performance of Li(4)SiO(4) material are reviewed. Additionally, potential research thoughts and trends are also suggested.
