The improvement of photocatalytic activity of g-C3N4 is expected for its advanced applications but remains a challenge due to the limitations of current strategies, such as single function, inefficiency, and uneconomical. Herein, a modified g-C3N4 with improved interface properties is constructed through the modulation of the ionic microenvironment affected by ionic liquids (ILs) and exhibits a 2.3-fold enhanced photodegradation efficiency and a 3.5-fold enhanced reaction rate relative to pristine g-C3N4. It has demonstrated excellent performance in photo-therapy bacterial-infected wounds. Theoretical calculation indicated that the precursor can be regulated by designing the specific ILs microenvironment to form “ILs-Mel” clusters due to the diversity of interaction energy and electrostatic potential. The cluster results in uneven stress on the 2D plane, further inducing the reconstruction of the microstructure. The synergistic effect of cations and anions of ILs on regulating the interface properties of g-C3N4 due to the change of skeleton structure during thermolysis of ILs. The microstructure, surface, and optical-electrical properties can be adjusted by selecting different cations of ILs, and the custom-made band structure and wettability can be obtained by selecting different anions. This work provides a facile strategy to modulate the interface properties of g-C3N4 by building specific a microenvironment of precursor.

离子液体微环境调节 g-C3N4 的界面特性，提高光降解和感染伤口愈合治疗的性能
gC 3 N 4光催化活性的提高有望用于其先进应用，但由于当前策略的局限性，如功能单一、效率低下和不经济等，仍然是一个挑战。在此，通过调节受离子液体（IL）影响的离子微环境，构建了具有改进界面性质的改性gC 3 N 4 ，并且相对于原始gC 3 ，其光降解效率提高了2.3倍，反应速率提高了3.5倍N 4 。它在光疗细菌感染伤口中表现出优异的性能。理论计算表明，由于相互作用能和静电势的多样性，可以通过设计特定的ILs微环境来调节前体形成“ILs-Mel”簇。簇导致二维平面上的应力不均匀，进一步诱导微观结构的重建。由于ILs热解过程中骨架结构的变化，ILs的阳离子和阴离子对gC 3 N 4界面性质的协同作用。通过选择不同的离子液体阳离子可以调节其微结构、表面和光电性能，通过选择不同的阴离子可以获得定制的能带结构和润湿性。这项工作提供了一种通过构建特定前驱体微环境来调节 gC 3 N 4界面性质的简便策略。
