Abstract
An oxidative method for water is provided. The oxidative method includes providing a compound having properties of a p-type semiconductor and an n-type semiconductor; obtaining a mixture by adding the compound to the water; and illuminating the mixture using a light source to excite the compound.
Claims8
An oxidative/reductive method for water, comprising:
- providing a graphene particle having a p-type conductivity domain and an n-type conductivity domain, wherein the graphene particle contains graphene oxide;
- obtaining a mixture by adding the graphene particle to the water;
- and
- illuminating the mixture by using a light source, wherein the graphene particle is excited by the light source, and the water is decomposed by the graphene oxide to generate hydrogen gas or oxygen gas.
