Copper catalysts supported on porous aromatic frameworks for the 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 SiO ₂ -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-NH ₂ 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.
