摘要

•A novel nonmetal 2D/3D g-C3N4 homojunction was constructed via the facile surface in-situ polymerization process.•The nonmetal 2D/3D g-C3N4 homojunction displayed the dramatically enhanced photocatalytic degradation performance.•The improved charge separation efficiency results from synergetic effect of structural coupling and energy band controlling.•This work develops a feasible strategy for fabricating new nonmetal homojunctions to improve photocatalytic activity.
