Highly visible-light-sensitive photocatalysts are developed with the formation of surface nanostructures controlled by plasma-surface interaction, as follows : (1) Nitrogen-doped surface layer are formed on surfaces of TiO_2 and transition metal-doped TiO_2, respectively. It becomes apparent that their band-gaps become narrow with the formation of the surface layer. (2) Cu-contained layer is formed on a surface of TiO_2 with plasma CVD using organometallic compound. Multi-electron-reactivity of the plasma CVD-treated TiO_2 can realize with the contained Cu reduced by visible-light-excited electrons. (3) Composite composed of Nb-doped TiO_2 as n-type semiconductor having nitrogen-doped surface layer and CuBi_2O_4 as p-type semiconductor shows Z-scheme mechanism in which visible-light-excited electron can be transferred form the n-type to the p-type semiconductor after each visible-light excitation in the semiconductors.

高度可见的光敏感光催化剂是通过由等离子体表面相互作用控制的表面纳米结构的形成，如下所示：（1）分别在TIO_2和过渡金属掺杂TIO_2的表面上形成氮气掺杂的表面层。显然，随着表面层的形成，它们的带隙变得狭窄。 （2）使用有机金属化合物在TiO_2的表面上形成含Cu的层。血浆CVD处理的TIO_2的多电子反应性可以通过可见光启用的电子降低包含的Cu来实现。 （3）由NB掺杂TIO_2作为N型半导体组成的复合材料，具有氮气掺杂的表面层和Cubi_2O_4作为P型半导体，显示了Z-Scheme机制，其中可见光光线的电子可以在每种p-evendpe中的n-type convectuctions convectuctions convectuctions convectuctions convectuctions convectuctions convectuctions convectuctions convecipition。
