A review of patent publications on preparation, deposition, characterization, and application of the catalytic
coatings is given in this paper with view on their application in microstructured reactors for heterogeneous gas-phase
processing. The paper consists of two main parts: in the first part the total overview of patents, the distribution by countries
and patent applicants is shown. The main topics (coatings preparation, application, removal etc.) are discussed in the
second part of the review, including description of some selected patent publications. The aim of the present review is to
show the ‘hot’ topics of patent publications on catalytic coatings and the main interests of the big patentees; special attention
is given to catalytic coatings on the channel walls in microstructured reactors.
Keywords: Catalytic coatings, deposition techniques, microstructured reactors, patents.
