Under the hydrothermal condition, the surface of sepiolite was restored with silicate and Ni was precipitated on the restored sepiolite by precipitating‐reducing method. The surface of the samples was characterized by SEM, BET and XRD. The catalytic ability was examined by hydrogenation of toluene in gas phase over the silicate restored Ni/sepiolite catalyst. The experimental results show that distribution of Ni over the surface of the sample was even with bare aggregation and can be controlled, the ability of anti‐aging of this catalyst was about ten times higher than that prepared by impregnation method at the same reactive condition.
