The macroporous α-Fe₂O₃tulular tubular hierarchical structure has been synthesized by a facile template method. The macroporous α-Fe₂O₃ has high surface area (120 m²g^-1) and pore volume (0.967 cm³g^-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.

大孔的α-Fe ₂ ö ₃ tulular管状分层结构已由一个浅显模板的方法合成。大孔的α-Fe ₂ ö ₃具有高的表面积（120米²克^-1）和孔体积（0.967厘米³克^-1）。为了证明其超快的传质速率，该多孔的α-Fe ₂ ö ₃被用来除去来自刚果模拟废水红色。刚果吸附过程在大孔的α-Fe红₂ ö ₃只能5分钟，这是比其它报道了类似的材料快得多内完成。这种大孔的α-Fe₂ O ₃对于催化剂载体，吸附剂和传感器非常有用，其中活性位点的可及性是提高性能的重要因素。
