| 英文摘要 | catalytic wet peroxide oxidation (cwpo) of m-cresol over fe/gamma-al2o3 and fe-ce/gamma-al2o3 was studied. catalysts were prepared using the incipient wetness impregnation method, and characterized using xrd, xps, bet, and sem techniques. effects of ce loading, h2o2 dose, initial solution ph, reaction temperature, and m-cresol concentration on the cwpo of m-cresol were investigated in detail. the results showed that an addition of 2 mass % ce into fe/gamma-al2o3 resulted in better catalytic activity over a wider ph range and at lower reaction temperatures, and with lower h2o2 consumption than when using the fe/gamma-al2o3 catalysts only. the best catalytic activity was obtained using the fe-ce-2 catalyst with complete m-cresol degradation, 43.2 % toc removal using 100 mmol l-1 h2o2 at ph 4.0 and 60 degrees c in 90 min. xps showed that an addition of 2 mass % ce increased the density of non-lattice oxygen on the catalyst surface facilitating electron transfer and thereby producing radicals and promoting catalytic activity in the cwpo reaction. recycling experiments showed that fe-ce-2 retained its activity even after six subsequent runs without changing the morphology, and that iron ions did not significantly leach from the catalyst surface.
