High Thermal Stable Hollow Mesoporous Nanotubes, Preparation and Application for the Same

A method for manufacturing a hierarchical structured nanotube, comprising the steps of

• (A) providing a polymeric template wherein the polymeric template includes a plurality of organic polymeric nanowires;
• (B) forming an inorganic layer over a surface of the plurality of organic polymeric nanowires of the polymeric template;
• and
• (C) thermal heating the surface to form the polymeric template having the inorganic layer so as to permit a portion of atoms of the organic polymeric nanowire to migrate into the inorganic layer.

A reaction unit apparatus, comprising:

• a reaction chamber, wherein the reaction chamber has at least one hierarchical structured nanotube;
• at least one inlet connecting with the reaction chamber;
• and
• at least one outlet connecting with the reaction chamber;
• wherein, a fluid enters into the reaction unit apparatus through the inlet, engages in a reaction with at least one hierarchical structured nanotube, and discharges through the outlet.
