Catalytic Activities of Alkoxide-derived LaAlO₃ for Ethanol Steam Reforming Processing

Abstract

Alkoxide-derived lanthanum aluminate (LaAlO₃: LAO) nanoparticles were obtained at 1023 K. Experimental process parameters such as the starting reagents and the process temperature were optimized to obtain LAO with a large surface area. Consequently, LAO with 29 m²/g was attained at 1073 K. This surface area was approximately twice that of the conventional chemical solution deposition using polymerized complex method. The catalytic activity for the ethanol steam reforming process of the obtained LAO was estimated using a conventional fixed bed reactor. Results show that the highest hydrogen yield of approximately 40% was attained using alkoxide-derived LAO. The catalytic activity was higher than that of LAO derived from the conventional preparation technique.
