Chemical Vapor Deposition Methods for the Controlled Preparation of Supported Catalytic Materials

摘要

The controlled preparation of heterogeneous catalysts is a gentle art, and various procedures are at the disposal of chemists to elaborate efficiently supported catalysts. However, perfectly designed catalysts still remain a challenge: indeed, an heterogeneous catalyst consists of a solid support and an active phase each presenting their own physical and chemical properties, which can evolve during the preparation. Many studies have been devoted to liquid-phase methods to prepare supported catalysts, and so, according to our own experience and to their promising development, we have focused our attention on gas-phase procedures, i.e., chemical vapor deposition (CVD) and related techniques.
