“…In addition to the renewable energy, carbon capture, utilization, and storage (CCUS) is also considered to be a significant solution to mitigate CO 2 emissions during the utilization of carbon-containing fuels. Generally speaking, pure CO 2 is obtained through various capturing methods and is then stored geologically or used in food industry, liquid or gaseous fuels synthesis, and oil extraction. − Chemisorption based on recyclable solid sorbents has been intensively studied and has gradually emerged as a sufficiently competitive carbon capture method. Particularly, Li 4 SiO 4 is considered as a promising high-temperature sorbent for its high adsorption capacity (approximately 0.3 g/g) and the excellent cyclic stability .…”

Renewable energy and electric vehicles are well-acknowledged strategies for reducing CO 2 emissions, and their development relies heavily on the core of energy storage systems using lithium-ion batteries. However, recycling of lithium-ion batteries is far from mature, and massive abandonment of spent batteries would lead to severe environmental pollution. Meanwhile, the shortage of lithium resources brought about by the rapid development of lithium-ion batteries, especially LiFePO 4 , significantly drives up the preparation cost of Li 4 SiO 4 as a promise sorbent and greatly limits its application as a CO 2 capture scheme. Hence, a strategy is urgently needed to alleviate the lithium resource contradiction between energy storage and CO 2 mitigation. Herein, we report a novel concept in recycling spent LiFePO 4 battery to prepare high-efficiency and low-cost Li 4 SiO 4 sorbents for CO 2 capture. The obtained Li 4 SiO 4 sorbents demonstrate very stable CO 2 capacities of 0.27− 0.28 g/g in a typical test up to 80 cycles, a leading level in CO 2 capture, while the cost is only 1/6 of the conventional preparation process. It suggests that the concept of recycling spent LiFePO 4 for CO 2 capture has broad implications on resource utilization of energy waste and the mitigation of CO 2 emissions.

“…The reduction of CO 2 to valuable chemicals and fuels to mitigate the greenhouse effect has received wide attention. 118,119 However, there are two major obstacles that limit its development, i.e., the CO 2 adsorption energy barrier 120,121 and difficulties in precisely controlling the selectivity of products. 122 Recently, Mo 2 C(T x ) was applied in the CO 2 reduction reaction as a new type of catalyst.…”

“…In a typical cycle, CO 2 is stored on the DFM upon contact with a CO 2 -rich stream (adsorption step); the adsorbed CO 2 is then transformed into methane upon reaction with H 2 (hydrogenation step). In DFM formulations, an alkaline or alkaline earth CO 2 adsorbent phase (typically Na or Ca) and a metal active for the CO 2 methanation reaction (typically Ru and/or Ni) are dispersed over a high-surface-area, nonreducible support. − The coupling of adsorption and reduction capabilities in a single solid allows us to avoid the energy-intense thermal or pressure swing that is usually requested in the CO 2 capture/release cycle to regenerate the adsorbent. − In fact, in the case of DFM, the thermal input required for CO 2 release from the storage sites is supplied by the exothermic methanation reaction.…”

In this work, we discuss the role of different atmospheres and process conditions on the catalytic performances of Ru- and K/Ba-based dual-function materials (DFMs) for CO2 capture and methanation. By a combination of microreactor experiments and Fourier transform infrared (FT-IR) spectroscopy, we clarify the effect of temperature and H2 partial pressure during the hydrogenation step and the effect of water and oxygen during the CO2 adsorption step. In particular, we show that between 250 and 400 °C CO2 is rapidly adsorbed as bidentate carbonates on the basic sites (K or Ba) and as CO on Ru metal surfaces with decreasing storage capacity with increasing temperature. Increasing the operating temperature and the H2 partial pressure, the methanation rate of the bidentate carbonates increases. We also show that during the CO2 capture step, water not only reduces the amount of CO2 adsorbed by competitively adsorbing on basic sites but also changes the nature of the adsorbed carbonates, increasing their ionic character and hence their stability. This is observed in the case of both a K-based DFM and a Ba-based DFM, though in the case of the alkaline earth, the phenomenon is more evident. Finally, we point out that the presence of O2 during the CO2 capture step removes metallic Ru as CO adsorption site and reduces the amount of bidentate carbonates, possibly due to the additional presence of water formed upon Ru reduction in the methanation step. The information presented in this work is of interest to improve the design of DFMs to be used for flue gas, where the partial pressure of water and oxygen is relevant.
