This is gonna be a new thread to discuss possible photocatalyst for electron extraction. I personally have accepted the water bath fuel cell is an ultrasonic device such as a pond fogged and the charged fog is the prestige dandy charged water Stan speaks on. See my post about 3000ml fogged for more info related to this.

This topic will deal with looking for photocatalyst that will produce an unstable isomer of water using pure water vapor.

Found this air filter that kinda operates in the way we’re looking for. It is a pic of a photocatalytic air filter.
Here’s a link explaining how they operate. We need a version that does reduction oxidation to pair the O2 and H2 pairs together.

This is a link to research concerning water splitting from light while producing an electrical output.

This is the study materials for this class.
Splitting of pure water vapor (fog) using photocatalyst.

Here is inside electrode for submersed fuel cell. It has been flame spray coated with titanium dioxide, copper doped zinc sulfide and it looks to have iron oxide on it now as well.
The outside is free of coating at the moment I need to finish with electron bands and holes. Which I know about but don’t know the math or my electron bonds well enough to zero in on coatings. I’m just trying best known combination. This cell produces tiny bubble for awhile in distilled water for a period of time when completely dry.

So until the cells net charge is saturated and capacitor or cell is charged I need to try neon transformer again maybe with this cell.. Maybe???

I’m going to try coating outside with blue lin chalk through spray gun. Be nice if blue dye didn’t cook up when being applied.

Also I’d like to try a version where the cells are coated and fired in a kiln.

I used straws to space them. My method using weed wackier line would probably damage coat pressing them together.
Not that touching it with my fingers doosen’t since it’s essentially a semiconductor.

I built this before my 7 year vacation.
Solar Powered Water Fuel Cell

A version of Stan Meyer fuel cell. The inner cell has a flame sprayed coating of titanium dioxide and copper doped zinc sulfide. No electrical input and as of yet I have not tried to measure an output. I will post it when I get a measurement. It won’t be much at all given the bubbles being produced.

Thats a cool technologz, FI3..
What part is consumed during the process?


cheers!

Hi Steve,

   I don’t have the answer you’re looking for at the moment. The chemistry is complicated. I pulled this info concerning what I know for sure about what coatings are on the piece that generates under light. I made it by just trying different t mixes. There are a few other things in it like Copper doped Zinc Sulfide or glow in the dark powder. Also seems I should’ve fired it a couple times before using it to further cure it. After reading this I probably should’ve coated the TiO2 on top of the Ti4O7 and fired it on low temps to cure it to the surface of Ti4O7

Note : When the TiO2 is flame sprayed on the SS it turns into Ti4O7.

Info from:
http://tdma.info/what-is-titanium-dioxide/

As a photocatalyst, titanium dioxide can be added to paints, cements, windows and tiles in order to decompose environmental pollutants. As a nanomaterial (see below), it can also be used as a crucial DeNOx catalyst in exhaust gas systems for cars, trucks and power plants, thus minimising their environmental impact.

Researchers are discovering new potential uses for titanium dioxide in this form. This includes clean energy production.

As a photocatalyst, it has also been shown that TiO2 can carry out hydrolysis (breaking water into hydrogen and oxygen), and the collected hydrogen can be used as a fuel.



Info From
http://www.chinathermalspray.com/html/PRODUCT/list_15_1.html

The titanium black ceramic material has the following prominent characteristics:
      1. High electrical conductivity, similar to metal: Among them, the Ti4O7 phase, its single crystal conductivity can reach 1500 S/cm and its coating’s conductivity is better than graphite material’s in practical application.
      2. Excellent chemical stability and corrosion resistance: It has high stability in strong acids (H2SO4, HNO3, HCl even HF) and strong base solutions. For example, its semi-corrosion cycle can reach 50 years in 4mol/L of sulfuric acid at room temperature. It is the best chemical resistance conductive material.
      3. Unique electrochemical property: After hydrogen evolution and oxygen evolution, its electric potential is high, electrochemistry is stable and working potential window is very wide. This exceeds all common electrode materials. For example, in 1mol/L of sulfuric acid at room temperature, the difference between oxygen evolution potential and hydrogen evolution potential of the titanium black electrode is nearly 4. 0 V. This let it have good application prospect in area of positive and negative electrode, Electrocatalytic carrier and advanced oxidation process(AOPs). As the electrode matrix material, it can be electroplated, chemical deposition or coated various metal oxide or precious metal catalysts. And the chemical bonding with these catalysts is good. The catalytic activity is almost constant and the effect is excellent.
      4. Microwave absorption property: The titanium black have strong microwave absorption property under temperature of 800 ℃. This property is better than silicon carbide material’s. It is a new kind of microwave auxiliary heating material and microwave waveguide material.

so what? photocatalyst are known for decades even rust can be used as a photocatalyst but you have to use light not electricity to activate the photocatalyst

Oxides of titanium can adsorb a lot of hydrogen on their surface so for any reaction that evolves hydrogen  it cause the hydrogen evolution to be much greater, especially titanium with noble metals such as palladium and platinum.
