Abstract:The macroporous alpha-Fe2O3 tubular hierarchical structure has been synthesized by a facile template method. The macroporous alpha-Fe2O3 has high surface area (120 m(2) g(-1)) and pore volume (0.967 cm(3) g(-1)). To demonstrate its ultrafast mass transfer rate, this porous alpha-Fe2O3 was employed to remove Congo red from simulated waste-water. The adsorption process of Congo red on macroporous alpha-Fe2O3 can be finished within only 5 min, which is much faster than those of the other reported similar materials. This macroporous alpha-Fe2O3 will be very useful for catalysts support, adsorbent, and sensor, wherein accessibility of active sites is an important factor to enhance the performance.
