Description
Summary:[Display omitted] •A simple template method was developed for synthesizing macroporous hollow Fe2O3.•This macroporous hollow Fe2O3 showed ultrafast transfer performance.•This macroporous Fe2O3 has high specific surface area and large pore volume. The macroporous α-Fe2O3 tubular hierarchical structure has been synthesized by a facile template method. The macroporous α-Fe2O3 has high surface area (120 m2 g−1) and pore volume (0.967 cm3 g−1). To demonstrate its ultrafast mass transfer rate, this porous α-Fe2O3 was employed to remove Congo red from simulated waste-water. The adsorption process of Congo red on macroporous α-Fe2O3 can be finished within only 5 min, which is much faster than those of the other reported similar materials. This macroporous α-Fe2O3 will be very useful for catalysts support, adsorbent, and sensor, wherein accessibility of active sites is an important factor to enhance the performance.
