In this paper, the mesoporous silica MCM-41 supporting nano zero valent iron (MSNZVI) composite was synthesized in a facile way and characterized by XRD, FT-IR, TEM and N2 adsorption–desorption. The catalytic activity of the as-prepared MSNZVI composite as a catalyst was evaluated on the p-nitrophenol reduction in the presence of excess NaBH4. And the rate constant is 4.89 × 10−3 s−1 when the mole...
