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 4.89×10−3s−1 when the mole ratio of NaBH4 to p-nitrophenol is 500. MSNZVI composite can be reused for at least five cycles with stable catalytic activity. Moreover, a possible catalytic mechanism of MSNZVI was proposed to explain the reduction of p-nitrophenol by NaBH4.
