【 摘 要 】

Carbon-fiber-supported NiO catalytic filters for oxidation of volatile organic compounds were prepared by electroless Ni-P plating and subsequent annealing processes. Surface structure and crystallinity of NiO film on carbon fiber could be modified by post-annealing at different temperatures (500 and 650 oC). Catalytic thermal decompositions of toluene over these catalytic filters were investigated. 500 oC-annealed sample showed a higher catalytic reactivity toward toluene decomposition than 650 oC-annealed one under same conditions, despite of its lower surface area and toluene adsorption capacity. X-ray diffraction and X-ray photoelectron spectroscopy studies suggest that amorphous structures of NiO on 500 oC-annealed catalyst caused the higher reactivity for oxidation of toluene than that of 650 oC-annealed sample with a higher crystallinity.
