Decomposition-Induced Preparation of High-Surface-Area Nb2O5 Materials for Catalytic Transesterification of Ethylene Carbonate to Dimethyl Carbonate
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.
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.
