Introduction Nano-TiO2 photocatalytic materials have broad application prospects in the field of water treatment.
Most of the present studies optimize the nano-TiO2 materials’ properties by means of doping metal ions and compositing semiconductors, etc [1].
Above all, it is of great significance to study, design and prepare the photocatalytic materials by this experiment to mix ZnO and TiO2 at the molecular level and add in trace amount of rare earth ions.
This experiment prepares the high activated nano-ZnO-TiO2 semiconductor materials by the sol-gel method.

Utilizing this advantage for preparing inorganic nanometer or the submicron materials with regular morphology is a brand-new field.
In addition, the development of novel materials requires smaller sized particles and additive powders with good dispersing properties in water in order to form a stable suspension [8].

Therefore, the research and development of a new technology which can smooth and cold process deformed surface,thin and long pipe, complex cavity and hard brittle materials is imperative[7]. the smooth processing technology of abrasive water jet is in the initial stage currently, the recearch of single abrasive particle removal mechanism has a guiding significance.
Water jet on the material have impacting and shearing action. the shock can increase the removal quantity, but reduce the surface integrity, shearing action can improve the surface quality of materials.
For example ,the incident Angle is adjusted 30 °As shown in figure 4, Through the observation of the material surface morphology can found that there are thickly dotted ordered arrangement tiny furrow in the picture, which explain when incidence angle reduced from 90 °, material removal way transforms from the messy fracture and flake way to ordered of furrows shear mode, so we can achieve the purpose of changing the surface morphology materials.
