Unconventional Pathways for Designing Silica-Supported Pt and Pd Catalysts With Hierarchical Porosity

Abstract Catalysis as a pillar of green chemistry is called on to improve the performance of the current chemical processes and to develop new and sustainable processes and products. In order to tackle the current challenges in sustainable chemistry, catalyst rational design approaches are necessary. Such approaches require tailoring tools for the catalyst preparation, which should also be environmentally friendly. This chapter starts by a brief review of the techniques for texture tailoring and catalyst functionalization, highlighting the high potential of hierarchical porous catalysts. Then, a few innovative techniques for the preparation of silica-supported Pt and Pd catalysts with hierarchical porosity are described.
