New photocatalytic materials for producing "green" hydrogen have been developed at Tomsk Polytechnic University (TPU). This was reported by the press service of the Ministry of Education and Science of the Russian Federation.
In traditional methods of hydrogen production for photocatalytic devices, zinc oxide is used. However, its particles do not provide sufficient electron transfer for splitting the water molecule.
Zinc oxide can be modified and transformed into nanostructures that will possess good semiconductor and optoelectronic properties. The synthesis of binary nanocomposite materials from tungsten disulfide and zinc oxide (WS2-ZnO) was carried out by the method of electrical discharge erosion of zinc granules in aqueous solutions of hydrogen peroxide with the simultaneous addition of nanostructured WS2 powder to the reaction zone.
The scientists managed to obtain gaseous hydrogen and oxygen at the counter electrode and the working electrode.
The research results showed that the obtained WS2-ZnO nanostructures have good potential for use as a photoanode material for photoelectrochemical water splitting in order to obtain hydrogen for use in "green" energy.
Earlier www1.ru reported that Rosatom State Corporation will open a hydrogen energy laboratory on the territory of SPbPU.
