## Description

- description: "　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. "
