Need enough supplies of electric power.These electric power may be the gained that generates electricity from solar panel so that cost increase and equipment it is complicated,
It is complex for operation step.Water oxygen and hydrogen, which is catalytically decomposed, using sunlight lower semiconductor material also many reported in literature, but
These methods can only decomposite a small amount of oxygen and hydrogen gas mixture, practical value are little, the separation consumptive material of mixed gas
Or power consumption, increase cost.Can search out low-material-consumption, low energy consumption, low cost oxygen manufacture new method it is extremely important.
In fact, the energy contained in sunlight can directly be switched to electron energy by metal oxide or ion, it is such
Water-molecule dissociation can not only be oxygen and Hydrogen Proton (H by metal oxide electrode+), while can also produce electronics.When with leading
These electronics are guided to the Hydrogen Proton (H that supply is come by anode migration on cathode electrode by line+) when, with regard to hydrogen can be reassembled into
Gas.So oxygen is discharged on anode and hydrogen is discharged on cathode respectively, the energy of light requirement, the consumption without electric energy.
It was found from thermodynamically, the electrode potential of itself will be promoted after more than metal oxide electrode absorbs luminous energy
With confess electronics, as long as this electrode potential be higher than water decomposition current potential, so that it may produce oxygen and Hydrogen Proton (H+).Aqueous solution
Middle Hydrogen Proton (H+) concentration difference, can make it rapidly to the low cathodic migration of concentration.At this point, the electronics generated on anode is drawn
It, just can be with proton (H to cathode electrode+) recombine and release hydrogen and reach dynamic equilibrium.It is this cleverly to design very much,
Electric energy can be converted light energy into decompose hydrone simultaneously to generate oxygen, efficiency high, without first being generated electricity again by solar panel
It decomposes hydrone, reduce efficiency.
There is substantial difference compared with traditional electrolysis, the utility model is without supply of electric power.Such as existing correlation

Platinum removes hydrogen and imflammable gas.Oxygen made from the utility model and hydrogen are respectively in anode and cathode collector；This practicality is new
Luminous energy is changed into electric energy by type without elder generation, as optical electro-chemistry decomposes high purity oxygen gas (CN104195588A processed
(201410444414.3)) light source is not only needed, additional power (power supply) is also wanted to power.Due to without photoelectric conversion process, nothing
All show that this mode energy conversion is the most efficient by theoretically analysis or actual motion, equipment is simple, of low cost, behaviour
Make simplicity, realize that optical electrical can directly generate pure oxygen with the mutual conversion of chemical energy.
From electrolysis aquatic products oxygen need electrical methods it is different, also with photodissociation production oxygen and hydrogen gas mixture method not
Together, the photo cathode used in the utility model is to convert light energy into electron energy directly to decompose water release oxygen on anode,
And assemble enough electronics on cathode and be supplied to H+Proton is converted into hydrogen, and pure oxygen is obtained in cathode zone.From root
The defects of electrolysis water/photodegradation water being overcome on this.
