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.
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.
