Modification of Catalytic Performance of Supported Pt Catalysts by Coverage with Silica Layers
Supported Pt catalysts were covered with hydrophilic or hydrophobic silica layers. Both silica-coated Pt catalysts showed high tolerance to high-temperature sintering of Pt metal particles. The coverage with hydrophobic silica enhanced the activity of Pt catalysts for alkene hydrogenation in hydrophilic solvents.
