Abstract

The purpose of this study is to adhere titanium, sodium and silver to the surface of woody biomass by low temperature plasma irradiation. As the woody biomass, wood powder and coffee grounds were used. First, those powder samples were ozonized by oxygen plasma irradiation. Next, TiCl4 gas, NaNH2 gas or AgNO3 gas plasma was generated in a quartz tube and the sample was irradiated in the tube. The composition of the sample surface was identified using an XPS. In the result, it was confirmed that three kinds of metals bonded to the wood powder. The hydrophilic property, photocatalyst, and sterilization characteristic of the wood powder were examined.
