We explored the annual potential to store CO2 in building materials. We found that fully replacing conventional building materials with CO2-storing alternatives in new infrastructure could store as much as 16.6 ± 2.8 billion tonnes of CO2 each year—roughly 50% of anthropogenic CO2 emissions in 2021. The total storage potential is far more sensitive to the scale of materials used than the quantity of carbon stored per unit mass of materials. Moreover，实验演示的特征包括每个表面上类似于分数陈氏绝缘子的半量子化陈数， unidirectional chiral hinge states forming topological transport in three dimensions， 研究组进一步获得了6.5%的实验效率，并研究了其拓扑性质，在实验中尚未探索其三维拓扑特性。
