Abstract

The methods used to deposit a catalyst on structured surfaces are reviewed. Physical methods such as PVD and chemical methods (sol–gel, CVD, direct synthesis, etc.) are described. The coating of catalysts based on oxide, zeolite or carbon support is detailed on various surfaces such as silicon or steel microstructured reactors, cordierite monoliths or foams, fibres, tubes, etc.

Graphical abstract

Methods used to deposit metal-on-oxide catalysts, zeolite catalysts or carbon-based catalysts on structured substrates (wall-reactors) are reviewed. Wet-procedures such as suspension or sol–gel as well as physical methods such as sputtering are explained and compared with some examples. A large range of substrates is concerned: silicon microreactors, ceramic monoliths, steel foams, etc.

Keywords: Washcoating; Coating; Alumina deposition; Carbon deposition; Catalytic film; CVD; PVD; Suspension; Sol–gel; Zeolite; Structured reactor; Wall-reactor; Microreactor
