[0032] 2. Preparation of filamentary photoanode
[0033] (1) Perform strong alkali hydrothermal treatment on the cleaned and dried titanium wire. The treatment method is to immerse it in a 10M NaOH aqueous solution, conduct a hydrothermal reaction at a certain temperature for a period of time, and then use 0.1 M is washed with HCl solution and deionized water, dried and sintered at 400-500°C for 30 minutes, wherein the optional hydrothermal reaction temperature is 100-160°C, and the reaction time is 2-12 hours.
[0034] (2) Put the titanium wire after the strong alkali hydrothermal treatment into the 40-50mM titanium tetrachloride solution for treatment, and then use B
[0035] Washing with alcohol and deionization, drying and sintering at 450-500°C for 30 minutes, wherein the temperature of titanium tetrachloride treatment is 70°C, and the treatment time is 30-40 minutes.
[0036] (3) The slurry used in the photoanode is titanium dioxide nanoparticles with a diameter of 20 n...
Embodiment 1
[0049] (1) cleaning. Cut the titanium wire into the required length, first use sandpaper to polish the surface to remove obvious impurities and polish it smoothly, and then use
[0050] Scrub with an aqueous solution containing detergent, then rinse with a deionized aqueous solution, then ultrasonically clean with deionized water, ethanol, and acetone for 10 minutes, take it out and dry it for later use.
[0051] (2) Treatment of titanium wire substrate. Put the cleaned titanium wire into the sintering furnace, sinter at 400°C for 5 minutes, and take it out after it naturally cools down to about 50°C.
[0052] (3) Preparation of photoanode. Apply the prepared titanium dioxide nanoparticle slurry on the treated (2) titanium wire surface
[0053] Then put it in an oven, dry it at 60°C, put it into a sintering furnace, sinter at 500°C for half an hour, take it out after naturally cooling down to 50°C, rinse the sintered photoanode with alcohol and bake it Dry, then put the...
Embodiment 2
[0059] (1) cleaning. With embodiment 1.
[0060] (2) Treatment of titanium wire substrate. Put the cleaned titanium wire into a 100ml reactor liner, and put 40ml into the liner
[0061] 10M NaOH solution, after tightening the reactor, put the reactor into a 120°C oven for hydrothermal reaction, after 2 hours of reaction, let it cool down to room temperature naturally, take out the reacted titanium wire, put it into 0.1 Soak in the HCl solution of M for 2 hours, take out the titanium wire, wash it with ethanol and deionized water respectively, dry it after cleaning, put it into the sintering furnace, and sinter it at 500°C for 30 minutes, after sintering Take it out when it drops to 50°C.
[0062] (3) Preparation of photoanode. Apply the prepared titanium dioxide nanoparticle slurry on the titanium dioxide treated in step (2).
[0063] Silk surface, all the other steps are with embodiment 1.
[0064] (4) Assembly of filament battery. With embodiment 1.
[0065] (5) Perf...
