专利汇可以提供Prodution of hydrogen from water using photogalvanic effect of polyacid ion专利检索,专利查询,专利分析的服务。并且PURPOSE: To produce titled hydrogen easily and inexpensively by using an aqueous alkyl ammonium salt soln. of polyacid of W or V as anolyte and an aqueous acid soln. as catholyte and irradiating light to the anolyte.
CONSTITUTION: An aqueous alkyl ammonium salt soln. 2 of polytungstic acid or polyvanadic acid is put into an anode chamber 1, and an aqueous acid soln. 5 is put into a cathode chamber 4 partitioned by a glass frit diaphragm 7. The anode 3 and the cathode 6 are connected by means of an electric wire 8, and the cathode 6 is covered with a gas burrette 9. When the aqueous soln. 2 is irradiated with light, photooxidation-reduction reaction takes place in the anode chamber 1, by which water is oxidized and produces hydroxy radical. The polyacid ions are reduced and the produced electrode active material releases electron with the anode 3 by the strong reducing power thereof. The electrons reach the cathode 6 through the wire 8 and react with the H
+ in the cathode chamber 4, thereby producing gaseous H
2 .
