Enhanced the Catalytic Performance of CeO2 by Tuning V5+ Doping Amount in Carbonylation of n-Butyl Amine with CO2
CO2 regeneration and reutilization is considered to be a green and effective route with highly potential for development. CeO2 showed high catalytic activity for the production of N,N′-dibutylurea through n-butyl amine and CO2. Herein, V-doped CeO2 with different molar ratios of V/Ce (Vx%-CeO2, x = 0, 0.4, 0.6, 0.8 and 1.0) were further successfully synthesized and firstly applied to the reaction of CO2 with n-butyl amine. The reaction results displayed the catalytic performance of CeO2 were prominently enhanced by doping V5+ and followed an order of V0.8%-CeO2 > V0.6%-CeO2 > V1.0%-CeO2 > V0.4%-CeO2 > CeO2. The reason for the changes in the catalytic activities of CeO2 with different doping amounts of V5+ could be closely related to the surface oxygen vacancy and surface weak acidity and weak basicity based on specific analysis of relevant characterization including XRD, BET, Raman, XPS, EPR and NH3/CO2-TPD.
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.
