Improving catalytic activity and stability by in-situ regeneration of Ni-based catalyst for hydrogen production from ethanol steam reforming via controlling of active species dispersion

For ESR reaction, a novel catalyst regeneration method was reported (2#). Results showed the catalyst regenerated by traditional method (1#) partially recovered initial catalytic activity, while the catalyst regenerated by new method can fully restored activity and stability, which were closely related with high metal dispersion and small particles size.278
