Willow or poplar catkins were carbonized to prepare carbon microtubes (CMTs) due to their natural micro-tubular structure. After carbonization at temperatures of 550-950 degrees C, CMTs with outer and inner diameters of 4-8 and 3-7 mu m were obtained. In addition to having a large and accessible inner tube, a small amount of nitrogen (similar to 1.8 at.%) and phosphorus (similar to 0.4 at.%) dopants cause CMTs prepared at 750 degrees C to be a cheap metal-free catalyst with good catalytic activity in the oxygen reduction reaction.
