We propose a new nitride photocatalyst of an n-n+-GaN structure to increase H2 gas generation. This structure consists of a thin lightly-doped n-type layer on a heavily-doped n+-type layer to realize an optimized depletion layer for optical absorption and highly conductive region, respectively. An optimized n-n+-GaN structure could generate much more H2 gas rather than a single n-GaN layer structure by about 1.4 times.
