Copper Catalysts Supported on Porous Aromatic Frameworks for Hydrogenation of Ethylene Carbonate
Hydrogenation of organic carbonates on heterogeneous catalysts is one of the ways of indirect conversion of carbon dioxide, which is essential for addressing the urgent problem of decarbonization. Cu-based catalysts are the most widely used in hydrogenation, but their properties strongly depend on the characteristics of the heterogeneous carriers used. Although SiO2-based catalysts are the most extensively studied, it is of interest to develop catalysts based on new types of carriers such as MOFs, COFs and PAFs. In the current work, a series of copper-based catalysts with different metal contents (2, 5, 10, 30 wt%) based on porous aromatic framework PAF-30 and its amino-functionalized derivative PAF-30-NH2 were synthesized and investigated in the hydrogenation of ethylene carbonate. The influence of reaction temperature, hydrogen pressure, concentration of ethylene carbonate in its solution in THF, copper content in the catalysts and reduction conditions on the activity of the catalysts was systematically studied. A high activity of 940 mgEC gcat−1 h−1 was attained with 30Cu-PAF-30-NH2 catalyst at 200 °C and 4 MPa H2 in 4 h.
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.
