The P4VP with the molecular weight of 12 K and the molecular weight distribution of 1.2 was synthesized via reversible addition‐fragmentation chain transfer polymerization. Then it was added to the system for the preparation of ZIF‐8 as a surfactant. A special two‐dimensional (2D) sheet was produced because P4VP could promote the lateral growth of ZIF‐8. Additionally, the pyridine group from P4VP chains could complex Au³⁺ followed by in‐situ reduction under UV light to form the 2D ZIF‐8/P4VP/Au ternary hybrids. The ternary layered ZIF‐8/P4VP/Au hybrids exhibited a good yield for epoxy carbonate of 71 % and the high time‐space yield of 3.22 h⁻¹ in the reaction of carbon dioxide with propylene oxide, which was much higher than 0.425 h⁻¹ of the conventional homogeneous catalyst KI. Besides, the ternary layered ZIF‐8/P4VP/Au showed good stability, the catalytic performance was unchanged after three cycles.

基于三元分层ZIF-8 / P4VP / Au杂化剂的高效CO2转化为环状碳酸酯的催化剂

通过可逆加成-断裂链转移聚合反应合成了分子量为12 K，分子量分布为1.2的P4VP。然后将其添加到制备表面活性剂ZIF-8的系统中。由于P4VP可以促进ZIF-8的横向生长，因此生成了特殊的二维（2D）图纸。此外，P4VP链上的吡啶基可以使Au ³⁺络合，然后在紫外光下原位还原形成2D ZIF-8 / P4VP / Au三元杂种。三元分层ZIF-8 / P4VP / Au杂化物在二氧化碳与环氧丙烷反应中表现出71％的环氧碳酸酯良好的时空产率和3.22 h ^-1的高时空产率，远高于0.425 h ^-1常规均相催化剂KI的制备。此外，三层ZIF-8 / P4VP / Au表现出良好的稳定性，三个循环后催化性能没有变化。
