Abstract: Two-dimensional (2D) crystalline carbon nitrides (CₓNᵧ) with graphene-like atomic structures but semiconducting nature are new appealing materials, and increasing interest has been focused on their synthesis, properties, and applications. Apart from the well-known graphitic carbon nitride (g-C₃N₄), other types of 2D CₓNᵧ nanocrystals including C₂N, C₃N and C₅N₂ are also successfully fabricated in recent years and their properties and potential uses in various fields have been widely investigated. Meanwhile, g-CN, C₂N2, C₂N₃ and C₅N have been theoretically predicted, and their properties and potential applications have also been researched. Until now, 2D crystalline CₓNᵧ compounds have demonstrated promising applications in photocatalysis, electrocatalysis, gas adsorption/separation, and energy storage devices, from both experimental and theoretical aspects, stemming from their unique geometric structures, tunable electronic properties, and high specific surface area. Herein, recent advances in the synthesis of 2D CₓNᵧ nanocrystals and their applications in various fields are summarized. Moreover, future challenges and opportunities for developing 2D CₓNᵧ nanocrystals for more broad applications including environmental remediation are also discussed.
