Abstract

Dimethyl carbonate (DMC) was synthesized using CO₂ and methanol by different CeO₂ catalysts obtained from functionalized metal–organic precursors. CeO₂ produced from 1,2,4-benzenetricarboxylic acid (BTC) exhibits the greatest catalytic activity. The results of catalyst characterization manifested that the content of oxygen vacancy and Ce³⁺ on the surface of the CeO₂ catalysts is affected by different organic ligand. At the same time, the content of Ce³⁺ is positively correlated with Hammett’s values. The high catalytic activity of CeO₂-BTC is due to the highest oxygen vacancy and Ce³⁺ content. The solvothermal time and calcination temperature had great influence on the catalytic properties of the CeO₂ catalysts.

源自 CeO2 的功能化金属有机前体用于催化合成二氧化碳和甲醇制碳酸二甲酯

利用功能化金属有机前体获得的不同 CeO2 催化剂，使用二氧化碳和甲醇合成了碳酸二甲酯（DMC）。由 1,2,4-苯三羧酸（BTC）制备的 CeO2 表现出最大的催化活性。催化剂表征结果表明，CeO2 催化剂表面氧空位和 Ce3+ 的含量受不同有机配体的影响。同时，Ce3+ 的含量与 Hammett 值呈正相关。CeO2-BTC 的催化活性高是因为其氧空位和 Ce3+ 含量最高。溶热时间和煅烧温度对 CeO2 催化剂的催化性能有很大影响。

期刊介绍： Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews. Topics covered include: • chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies; • synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs); • reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models; • applications of inorganic compounds, metallodrugs and molecule-based materials. Papers composed primarily of structural reports will typically not be considered for publication.
