Controlled morphology modulation of graphene carbon nitride (g‐C3N4) is successfully realized from bulk to 3D loose foam architecture via the blowing effect of a bubble, which can be controlled by heating rate. The loose foam network is comprised by spatially scaffolded few‐atom‐layer interconnected flakes with the large specific surface area, as supporters to prevent agglomeration and provide a pathway for electron/phonon transports. The photocatalytic performance of 3D foam strutted g‐C3N4 toward RhB decomposition and hydrogen evolution is significantly enhanced with the morphology optimization while its excellent optoelectronic properties are maintained simultaneously. Herein, the ultrathin, mono‐, and high‐quality foam g‐C3N4 interconnected flakes with controlled layer are facilely obtained through ultrasonic, thus overcoming the drawbacks of a traditional top–down approach, opening a wide horizon for diverse practical usages. Additionally, the layer control mechanism of 3D hierarchical structure has been explored by means of bubble growth kinetics analysis and the density functional theory calculations.

具有高度稳定的光电特性的3D泡沫支撑的石墨烯氮化碳
石墨烯碳氮化物（g-C 3 N 4）的形态控制可通过气泡的吹塑效果成功地实现，从散装到3D松散泡沫结构，可通过加热速率来控制。疏松的泡沫网络由具有大比表面积的空间支架式几个原子层相互连接的薄片组成，可作为防止聚结并为电子/声子传输提供途径的载体。形态优化可显着增强3D泡沫支撑的g‐C 3 N 4泡沫对RhB分解和析氢的光催化性能，同时保持其优异的光电性能。此处是超薄，单质和高质量的泡沫g‐C通过超声可以轻松获得具有可控层的3 N 4互连薄片，从而克服了传统的自顶向下方法的弊端，为各种实际应用打开了广阔的视野。另外，通过气泡生长动力学分析和密度泛函理论计算，探索了3D分层结构的层控制机制。
