By electroless nickel deposition on amino‐functionalized silica spheres, we prepared a novel catalyst SiO₂@NiO. Here, we study the catalytic properties by the reduction of 4‐NP. Applying UV/Vis spectroscopy, we see that 4‐NP is reduced to 4‐AP by reducing agent NaBH₄ in the presence of SiO₂@NiO in a few minutes. It is assumed that active nickel was stabilized by NiO, and obtain high catalytic activity nickel.
