Review of patent publications from 1990 to 2010 on catalytic coatings and different substrates, including microstructured channels : preparation, deposition techniques, applications

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.
