A series of Prussian blue analogs (PBAs) having a range of crystal structures and compositions was investigated as heterogeneous catalysts for the fixation of carbon dioxide (CO₂) to glycidol. The morphology of PBAs was modified, as confirmed by structural characterization, by varying the precipitation method. Of the prepared catalysts, the cubic Zn(II)-Co(III) PBA exhibited the highest catalytic activity (turn-over frequency up to 763 h⁻¹), selectivity (up to 94%), and recyclability for the cycloaddition of CO₂ to glycidol. In addition, branched polycarbonate polyols having tunable branching degree (0.15–0.61) and linear polycarbonates of relatively high carbonate content (up to 64.2%) were produced via ring-opening (multibranching) copolymerization of CO₂ and various epoxides using a highly amorphous Zn(II)-Co(III) double metal cyanide catalyst. Mechanistic pathways have been proposed by combining experimental results with computational studies.

研究了一系列具有一系列晶体结构和组成的普鲁士蓝类似物（PBA）作为将二氧化碳（CO ₂）固定为缩水甘油的非均相催化剂。通过改变沉淀方法，结构表征证实了 PBA 的形态得到了改变。在所制备的催化剂中，立方Zn(II)-Co(III) PBA对CO环加成表现出最高的催化活性（周转频率高达763 h ^-1）、选择性（高达94%）和可回收性₂缩水甘油。此外，通过CO的开环（多支化）共聚生产了具有可调支化度（0.15-0.61）的支化聚碳酸酯多元醇和碳酸酯含量相对较高（高达64.2％）的线性聚碳酸酯。₂和各种环氧化物，使用高度非晶态的 Zn(II)-Co(III) 双金属氰化物催化剂。通过将实验结果与计算研究相结合，提出了机理途径。
