Abstract
A supported catalyst for decomposing an organic substance that includes a carrier and catalyst particles supported on the carrier. The catalyst particles contain a perovskite-type composite oxide represented by AxByMzOw, where A contains at least one of Ba and Sr, B contains Zr, M is at least one of Mn, Co, Ni, and Fe, y+z=1, x>1, z<0.4, and w is a positive value that satisfies electrical neutrality. An organic substance decomposition rate after the supported catalyst is subjected to a heat treatment at 950° C. for 48 hours is greater than 0.97 when the organic substance decomposition rate before the heat treatment is regarded as 1, and an amount of the catalyst particles peeled off when the supported catalyst is ultrasonicated in water at 28 kHz and 220 W for 15 minutes is less than 1 wt % of the catalyst particles before untrasonication.
