In this work, we found that ethylenediamine can enrich the electron state of Ni and make the azobenzene easily desorb from the surface of the catalyst, which effectively inhibits the further hydrogenation to aniline and greatly improves the selectivity of azobenzene. When the ratio of Ni and ethylenediamine is 1:10, the yield of the azobenzene can reach 95.5%.
