The effective utilization of carbon fibers recovered during the thermal decomposition recycling of carbon-fiber-reinforced plastic (CFRP) was investigated. Carbon fibers have a uniform diameter and a suitable size for the use as a combustion catalyst for particulate matter (PM). Thus, in this study, carbon fibers were used as a template to synthesize hollow-form LaNiO3 perovskite-type oxide via the precursor accumulation method. The calcination temperature was lowered by the internal heat supply from the combustion of the carbon template. Hollow-form LaNiO3 exhibited the same chemical properties as LaNiO3 prepared via the common sol–gel method. The morphology of the hollow form decreased the bulk density of the catalyst, resulting in enhanced contact with PM and, consequently, high PM combustion efficiency.
