Abstract

Dimethyl carbonate is a building block in modern chemical synthesis and battery industry. The catalytic transesterification of ethylene carbonate and methanol is a sustainable route for the clean synthesis of dimethyl carbonate. In order to improve the catalytic activity of Nb₂O₅ materials, a one-pot decomposition-induced preparation approach for high-surface-area Nb₂O₅ was developed. By incorporation of dicyandiamide and adjustment of calcination temperatures, Nb₂O₅ materials with various surface areas (47–143 m²·g^− 1) were prepared. Compared with the traditional decomposition method, the synthesized Nb₂O₅-CN materials possessed larger surface areas and higher quantities of acidic sites. As heterogeneous catalysts, the Nb₂O₅-CN materials demonstrated high activity in the transesterification of EC to DMC. Under the reaction conditions of 140 °C and 4 h, the conversion of EC and the selectivity of DMC reached up to 63.6% and 100%, respectively.

分解诱导制备高表面积Nb2O5材料催化碳酸乙烯酯交换制碳酸二甲酯

碳酸二甲酯是现代化学合成和电池工业的重要原料。碳酸乙烯与甲醇催化酯交换反应是清洁合成碳酸二甲酯的可持续途径。为了提高Nb2O5材料的催化活性，研究了一锅分解法制备高比表面积Nb2O5的方法。通过添加双氰胺和调整煅烧温度，制备了不同表面积（47 ~ 143 m2·g−1）的Nb2O5材料。与传统的分解方法相比，合成的Nb2O5-CN材料具有更大的表面积和更多的酸性位点。作为非均相催化剂，Nb2O5-CN材料在EC到DMC的酯交换反应中表现出较高的活性。在反应温度为140℃、反应时间为4 h的条件下，EC的转化率和DMC的选择性分别达到63.6%和100%。图形抽象

期刊介绍： Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis. The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
