Rational Design of Hollow Multilayer Heterogeneous Organic Framework for Photochemical Applications

Abstract

Self-assembling of hollow organic framework is a focal point in nanotechnology for several decades. Herein, we emphasized a general and simple system to fabricate arbitrary type of hollow multilayer heterogeneous organic framework. The hollow organic framework nanospheres comprising of black phosphorus quantum dot, carbon nitride, and polydopamine (BPQD/g-C3N4@PDA) are fabricated by an electrostatic bonding method. Surprisingly, the self-assembly process of g-C3N4@PDA does not completely accord with the law of charge interaction, only positively charged g-C3N4 and negatively charged PDA can self-assemble to obtain the desired structure. Furthermore, BPQD was further loaded on the surface of g-C3N4@PDA to increase light utilization and strengthen the charges separation in the photochemical process. Benefited from the hierarchical structure and the hollow spherical morphology, the BPQD/g-C3N4@PDA show a significant photocatalytic H2 production activity and the ability of NIR trigger generation of ROS. This method provides a proof-of-concept of organic framework with precisely controlled morphology.
