PRODUCTION METHOD FOR OZONE GAS REDUCTION CATALYST SUPPORT AND CATALYST SUPPORT

摘要

Conventional ceramic substrates break easily with impact and are even more susceptible to breakage if the openings are made larger. Substrates made of thin stainless steel plate cannot be manufactured at low cost, small flow paths are difficult to form thereon, and flow paths are linear because of the honeycomb structure, which means that the flow paths need to be lengthened to increase the chance of contact between a catalyst substance and a reactant, which makes reducing the size of the structure difficult. To solve these issues, disclosed is an ozone gas reduction catalyst support which uses a porous body wherein a raw material of one sheet of metal mesh or a raw material of a plurality of laminated metal meshes have been sintered, as a substrate for the catalyst support and which forms an alumina thin layer, which supports a platinum group metal or a platinum group metal oxide catalytic substance dispersed thereon, on the surface of this substrate.
