평균 입자 크기와 겉보기 밀도가 작은 Ni 촉매가 우수한 촉매능을 보여주었으며, 이 Ni로 제조된 Raney Ni이 역시 뛰어난 촉매능을 나타내었다. Raney Ni의 제조온도로 750℃가 적당하였다. CO 화학흡착과 벤젠의 수소화 반응에서는 Ni과 Raney Ni의 최적 PTFE 혼합량은 각각 10 wt%, 5 wt%였으나, 전극반응 실험에서 Raney Ni의 경우는 10 wt%이었다. Raney Ni의 촉매능은 수소 활성화처리에 의해 상당한 영향을 받았다.

Ni with a small average particle size and apparent density showed a good catalytic activity, and Raney Ni prepared from these Ni powders also exhibited an excellent catalytic activity. It was found that the best preparation temperature of Raney Ni catalyst was about 750℃. For the chemisorption of CO and the hydrogenation of benzene, the optimal weight ratio of PTFE-binder to Ni and Raney Ni was 10 wt% and 5 wt%, respectively. For electrode reaction experiments, however, 10 wt% PTFE-bonded Raney Ni hydrogen electrode showed the best electrode performance. The catalytic activity of Raney Ni was considerably affected by the treatment of H₂ activation.
