外文摘要：Magnetically active, thermally stable, and ordered mesoporous resin (MOMR-200) and carbon (MOMC-200) monoliths were prepared by one-pot hydrothermal synthesis from resol, copolymer surfactant, and iron cations at high-temperature (200 C-a similar to), followed by calcination at 360 C-a similar to and carbonization at 600 C-a similar to. X-ray diffraction results show that both MOMR-200 and MOMC-200 have ordered hexagonal mesoporous symmetry, and N-2 isotherms indicate that these samples have uniform mesopores (3.71, 3.45 nm), high surface area (328, 621 m(2)/g) and large pore volume (0.31, 0.43 cm(3)/g). Transmission electron microscopy shows that iron nanoparticles, which are superparamagnetic in nature, are dispersed in the network. More importantly, the high temperature (200 C-a similar to) products exhibit much better stability than the samples synthesized at low temperature (100 C-a similar to). Interestingly, MOMC-200 has higher adsorption capacity for organic dyes when compared with commercial adsorbents (activated carbon and macroporous resin: XAD-4). Combining the advantages such as magnetically active, thermally stable networks, ordered and open mesopores, high surface area, large pore volume, adsorption of pollutants in water and desorption in ethanol solvent, MOMC-200 is potentially important for water treatments.
