Ni微粒子/CeO2担体によるアンモニア分解
MDR Open Deposited
For the extraction of hydrogen from ammonia at low temperatures, we have investigated the Ni-based catalysts fabricated by the thermal decomposition of RNi5 intermetallics (R = Ce or Y). The spinodal-like 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. The interlocking of Ni nanoparticles with the CeO2 framework was attributed to the high catalytic activity.
