Cross cut of the designed cell : 1 – proton conductive membrane; 2 – filter paper; 3 – photo sensitive anodic catalyst; 4 – catalyst for protons’ reduction; 5 – collecting netting; 6 – water.
Area of applications
The photo sensitive anode can be used for hydrogen generation from water in the reversible fuel cell with the option of hydrogen accumulation. The accumulated hydrogen can be used for electricity generation in the reversible cell in the direct regime of operation.
Brief description
The photo sensitive anodes were developed from photocatalysts based on a mixture of oxides of iron (II) and (III) carried on the 2D-sized carrier substrates with graphene or carbon subnitride. The schematic diagram of photoelectrochemical cell was designed and assembled to produce hydrogen from water.
Expected properties
Optimization of way for producing hydrogen by water splitting under the photo radiation.
Advantages
Photo anodes based on mixture of oxides of iron (II) and (III) carried on the 2D-sized carrier substrates with graphene or carbon subnitride gave the potential difference up to 360 – 380 mV. It allowed to produce hydrogen with productivity up to 14.9 mkmole/(gcath).
