    Abstract:
    Photocatalytic reactions, including hydrogen/oxygen generation, water splitting and hydrogen peroxide production, are regarded as a renewable and promising method to harvest and use solar energy. The key to achieving this goal is to explore efficient photocatalysts with high productivity. Recently, two-dimensional (2D) polymeric carbon nitride nanosheets were reported as efficient photocatalysts toward various products because of their outstanding properties, such as high specific surface area, more reactive sites, the quantum effect in thickness and unique electronic properties. This minireview attempts to overview recent advances in the preparation, structure and properties of crystalline and amorphous carbon nitride nanosheets, and their applications in photocatalytic hydrogen/oxygen evolution, water splitting and hydrogen peroxide production. We also thoroughly discuss the effect of defects, dopants and composites on the photocatalytic efficiency of these carbon nitride nanosheets. Finally, we outlook the ongoing opportunities and future challenges for 2D carbon nitride nanosheets in the field of photocatalysis.
