Functional Nanocomposites Based on Metal Oxides and a Hyperbranched Polymer for the Synthesis of Methanol from CO2

A synthetic approach to the composites based on mesoporous aluminum oxide coated with a thermally stable aromatic branched polymer (Al2O3–PPP, Al2O3–Fe3O4–PPP) is developed that provides reliable stability to Zn and Cr oxide nanoparticles. The presence of a thermally stable hydrophobic polymer layer on the surface of aluminum oxide is shown to facilitate the creation of efficient catalysts for the synthesis of methanol from CO2, which can work at elevated temperatures and pressures.
