Reaction of CO₂ with alcohols to organic carbonates is one of non-reductive CO₂ conversion methods. The catalysts are needed for this reaction, at the same time, effective H₂O removal methods are also needed because the yield of organic carbonates is strongly limited by the equilibrium. The development of heterogeneous catalysts for the synthesis of dimethyl carbonate from CO₂ and methanol, which is a model and typical reaction, is described. This is because heterogeneous catalysts are more suitable to the practical process than homogeneous catalysts from the viewpoint of the separation of catalysts from the products and the reusability of the catalysts. One of the reported heterogeneous catalysts is CeO₂, and it has been also reported that the combination of dimethyl carbonate synthesis from CO₂ and methanol with the hydration of nitriles such as 2-cyanopyridine, where both reactions are catalyzed by CeO₂, enabled high yield of the carbonate. In addition, the combination of CeO₂ catalyst + nitriles can be applied to the synthesis of a variety of linear-, cyclic (five- and six-membered ring)-, and poly-carbonates from CO₂ and corresponding alcohols.

CO ₂与醇的反应成为有机碳酸酯是非还原性CO ₂转化方法之一。该反应需要催化剂，同时，还需要有效的H ₂ O去除方法，因为有机碳酸盐的收率受到平衡的强烈限制。描述了用于从CO ₂和甲醇合成碳酸二甲酯的非均相催化剂的开发，该模型是典型的反应。这是因为从催化剂与产物的分离和催化剂的可再利用性的角度来看，非均相催化剂比均相催化剂更适合于实际方法。报道的非均相催化剂之一是CeO ₂并且，也已经报道了由CO ₂和甲醇合成碳酸二甲酯与腈（例如2-氰基吡啶）的水合的组合，其中两个反应均由CeO ₂催化，使得碳酸酯的高收率。另外，CeO ₂催化剂与腈的组合可用于由CO ₂和相应的醇合成各种直链，环状（五元和六元环）和聚碳酸酯。
