(57) [Summary] [Purpose] To obtain a highly active denitration plate-shaped catalyst by enhancing the peeling strength and abrasion resistance of the catalyst without metal spraying on the substrate. [Structure] Lath surface 1 of substrate 1 obtained by lathing a thin metal plate a and a plate-shaped exhaust gas denitration catalyst in which the catalyst composition 3 is supported on the lath 1b which is the through hole, the catalyst composition comprises titanium oxide, one or more oxides of molybdenum, vanadium, and tungsten, and a sulfate group. And, containing metal aluminum or water-insoluble aluminum, while preventing the strength reduction by selectively precipitating aluminum sulfate in fine cracks generated during catalyst production or during use, suppresses clogging of the catalyst pores, Prevents a decrease in activity. |
