    摘要: The sol-gel templating with the infusion of gas bubbles provides a process for synthesizing polymeric or gel materials while being templated with slow bubbling of various gases into the reacting media upon the polymerization or gelation stage. The process uses a source of gas, which is delivered at a desired rate and pressure via at least one inert tube directly into the reacting solution while the gel is being formed by sol-gel process. The tube(s) have a diameter selected to produce bubbles that result in the desired pore size and the number and placement of the tubes is selected to produce the desired pore structure and surface area in the gel template. The gel may be any gel capable of being formed by sol-gel process. The gas may be selected from carbon dioxide, methane, nitrogen, helium, argon, oxygen, hydrogen, propane, ethane, propylene, ethylene, air, and n-butane and other inert gases.
