Combined calcium-copper materials based on calcium zirconate (CaO/CuO/CaZrO₃) for Calcium-Copper Chemical Looping (Ca-Cu Looping) have been synthesized using a scalable wet chemical method and characterized by powder X-ray diffraction (PXRD) with Rietveld refinement, temperature-programmed reduction (H₂-TPR) and oxidation (O₂-TPO), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and 45–50 cycles in a thermogravimetric analyser (TGA) representing realistic Ca-Cu Looping conditions. A material at 50 wt% active CuO loading and a CuO/CaO weight ratio of 2 deactivated due to copper migration and agglomeration, while materials with 40 wt% active CuO loading were stable throughout TGA cycles at CuO/CaO ratios of 2 and 10. 40 wt% CuO loaded combined CaO/CuO/CaZrO₃ materials are promising candidates for Ca-Cu Looping with a demonstrated tuneable and stable CuO/CaO ratio (≥ 2 [wt/wt]) that could lead to process intensification. The maximum CuO loading for the investigated materials is likely found in the range of [40, 50) wt%, subject to the constraints of Ca-Cu Looping relevant CuO/CaO ratios (≥ 2 [wt/wt]) and the performed TGA testing.

使用可扩展的湿化学方法合成了基于锆酸钙（CaO / CuO / CaZrO ₃）的钙铜复合材料，用于可扩展的钙铜化学成环（Ca-Cu环化）并通过粉末X射线衍射（PXRD）表征Rietveld精炼，程序升温还原（H ₂ -TPR）和氧化（O ₂-TPO），扫描电子显微镜（SEM），能量色散X射线光谱（EDS）和热重分析仪（TGA）中的45–50个循环，代表了实际的Ca-Cu循环条件。由于铜迁移和团聚，活性CuO负载量为50 wt％且CuO / CaO重量比为2的材料失活，而具有40 wt％活性CuO负载的材料在整个TGA循环中以2和10的CuO / CaO比稳定。负载40 wt％CuO的组合CaO / CuO / CaZrO ₃这种材料具有可调节和稳定的CuO / CaO比（≥2 [wt / wt]），有望成为制程中强化加工的理想选择。受Ca-Cu循环相关CuO / CaO比（≥2 [wt / wt]）和所进行的TGA的限制，所研究材料的最大CuO负载量可能在[40，50）wt％的范围内。测试。
