摘要

Abstract

The utilization of solid wastes to prepare Li

SiO

based CO

adsorbents and thermochemical energy storage (TES) materials has recently garnered significant interest. Considering practical application conditions

the influence of CO

concentration and temperature fluctuations on adsorbent performance remains a key research focus. Among various waste materials

waste clay bricks are particularly suitable for Li

SiO

synthesis due to their high SiO

content (60%% to 70%)

while enabling waste valorization. Furthermore

it has been demonstrated that heteroatoms present in the waste materials positively influence the CO

adsorption performance of Li

SiO

-based adsorbents. In this study

SiO

was synthesized for the first time directly from waste clay bricks without pretreatment. Comprehensive characterization revealed that the resulting Li

SiO

-based adsorbent exhibits outstanding performance:a high CO

capture capacity (27.9% (mass))

excellent cycling stability

and remarkable thermal energy storage capability (876.4 kJ·kg

- 1

). These superior properties position it as one of the most promising high-temperature adsorbents for simultaneous CO

capture and thermal energy storage (TES) from fossil fuel flue gase. Moreover

the adsorbent maintained excellent stability under fluctuating temperature and CO

concent

ration. Even at 20% (vol) CO

and 500

◦

it achieved a high capacity of 25.7% (mass)

reaching equilibrium within 15 min. This CO

capture performance is truly impressive.
