The utilization of carbide slag, an industrial by-product, as a resource to prepare value-added products has a profound impact not only for sustainable synthesis and the circular economy but also for CO reduction. Herein, we report the very first example of the controlled multi-dimensional assembly of calcium carbonate particles at the micrometer scale with industrial by-product carbide slag and CO. Calcium carbonate particles of distinctly different sizes, shapes, and morphologies are obtained by finely tuning the assembly conditions. This strategy yields diverse assembled structures, including simple cubic, mulberry-like assembled unit, stacked cubic polycrystalline, and rotated polycrystalline structures, using the same starting materials. This innovative approach not only highlights the adaptability and efficiency of utilizing industrial by-products via multi-dimensional assembly but also provides new insights into the potential applications of the resulting calcium carbonate.
将工业副产品电石渣作为一种资源用于制备增值产品，不仅对可持续合成和循环经济具有深远影响，而且对减少二氧化碳排放也具有重要意义。在此，我们首次报道了利用工业副产品电石渣和二氧化碳在微米尺度上对碳酸钙颗粒进行可控的多维组装。通过精细调节组装条件，可以获得尺寸、形状和形态明显不同的碳酸钙颗粒。使用相同的起始原料，该策略产生了多种组装结构，包括简单立方结构、桑椹状组装单元、堆叠立方多晶结构和旋转多晶结构。这种创新方法不仅突出了通过多维组装利用工业副产品的适应性和效率，而且为所得碳酸钙的潜在应用提供了新的见解。
