The development of cost-effective heterogeneous catalytic system for the synthesis of organic carbonate from CO₂ and epoxide is of great importance. A series of mesoporous organic polymers (MOP-0, MOP-1, MOP-2, and MOP-3) were prepared through facile one-pot polycondensation of commercially available, low-cost melamine and monoaldehydes. These MOPs represent a novel kind of metal-free, recyclable heterogeneous catalysts for the reaction of CO₂ with epoxides to form cyclic carbonates through hydrogen-bonding interaction. Moreover, hydroxyl functionalities in MOPs show a critical effect on their performance in CO₂ capture and conversion. The CO₂ adsorption capacity of these MOPs can be significantly enhanced by increasing the –OH portions in MOPs. Particularly, by introducing –OH group into the MOP structure (MOP-3 vs. MOP-0), the CO₂ adsorption capacity under 1 bar at 273 K can be increased by 39% from 82.4 mg g⁻¹ (MOP-0) to 114.4 mg g⁻¹ (MOP-3).

从CO ₂和环氧化物合成有机碳酸酯的具有成本效益的非均相催化体系的开发具有重要意义。通过市场上可买到的低成本三聚氰胺和单醛的便捷一锅式缩聚反应，制备了一系列介孔有机聚合物（MOP-0，MOP-1，MOP-2和MOP-3）。这些MOPs代表了一种新型的无金属，可循环利用的非均相催化剂，用于CO ₂与环氧化物通过氢键相互作用形成环状碳酸酯。而且，MOP中的羟基官能度对其在CO ₂捕获和转化中的性能显示出至关重要的影响。一氧化碳₂通过增加MOP中的–OH部分，可以显着提高这些MOP的吸附能力。特别是，通过在MOP结构中引入–OH基团（MOP-3与MOP-0），在273 K下1 bar下的CO ₂吸附容量可以从82.4 mg g ^-1（MOP-0）提高39％。至114.4mg g ^-1（MOP-3）。
