Abstract
In the porous substrate loaded with porous nano-particles structure and one-step micro-plasma production method thereof, since the micro-plasma system enhances the electron density and promotes reaction speed in the reaction without generating thermal effect, the method may be performed at an atmosphere environment. The nano-particles also can be quickly obtained by aforementioned micro-plasma system. The electromagnetic field generated by the micro-plasma can drive the nano-particles to be loaded onto the porous substrate in a one step, rapid and low cost process to improve the conventional techniques which require a relatively long procedure time and a complicated process.
