Abstract: |
The invention discloses a preparation art, which belongs to the preparation art of photo-hydrolysis nanometer electrode. Particularly, the invention relates to a preparation method, which utilizes solar energy for water decomposition and production of hydrogen nanometer electrode. The invention uses the synthetic titanium oxide nanometer microspheres and other semiconductor materials, such as zinc oxide , to construct lamellar nanometer electrode. The application of lamellar doping method accelerates an efficient separation of electron and cavity, the titanium oxide nanometer microsphere structure increases contact area of the electrode surface and the electrolyte, the material is provided with high light conversion efficiency and photolysis efficiency, which improve the photo-hydrolysis efficiency. The preparation method has a simple manufacturing process, which decreases the manufacturing difficulty of semiconductor nanometer composite material and simplifies the implementation process of the electrode. Thus, the invention has a potential application value. |
