Claim 0:
1. A photoelectrochemical cell for water splitting, comprising:
a GaON/ZnO photoelectrode,
wherein the GaON/ZnO photoelectrode comprises:
a metal oxide conducting substrate selected from the group consisting of a fluorine doped tin oxide film and an indium tin oxide film; and
a nanoarchitectured photocatalytic material deposited onto a surface of the metal oxide conducting substrate;
wherein the nanoarchitectured photocatalytic material comprises:
zinc oxide nanoparticles; and
gallium oxynitride nanoparticles interspersed in the zinc oxide nanoparticles;
wherein the zinc oxide nanoparticles form a framework;
wherein the gallium oxynitride nanoparticles are interpenetrated in the framework; and
the gallium oxynitride nanoparticles are uniformly distributed in the framework;

a counter electrode; and
an electrolyte solution comprising water and an inorganic salt in contact with both the GaON/ZnO photoelectrode and the counter electrode.
