摘要

Mesoporous nickel silicate molecular sieves having hexagonal structure (Ni/MCM-41, Ni-Cr/MCM-41, Ni-Ru/MCM-41) were prepared by direct synthesis, characterized and tested for the liquid-phase oxidation of styrene with H_2O_2. NiCr-MCM-41 catalysts have the highest conversion and selectivity to benzaldehyde. Leaching was evidenced for chromium and ruthenium at reaction temperature of 343 K.
