WebIn addition, the construction of the Z-scheme photocatalyst is inspired by the natural photosynthesis process and the S-scheme photocatalyst is named for its staggered band structure. Besides, it is emphasised that the two semiconductors constituting S-scheme photocatalyst are referred to as oxidation photocatalysts and reduction photocatalysts.
