説明:

　For the extraction of hydrogen from ammonia (NH3) at low temperatures, we have investigated the Ni-based catalysts fabricated by the thermal decomposition of RNi5 intermetallics (R = Ce or Y). The interconnected microstructure formed via phase separation between the Ni catalyst and the resulting oxide supporter was observed to evolve via the low-temperature thermal decomposition of RNi5. The resulting Ni/CeO2 nanocomposite exhibited a superior catalytic activity of ~25% at 400 ℃ for NH3 cracking.
