![]() ![]() Introduction Reactive oxygen species (ROS), chemical species formed upon incomplete reduction of oxygen, 1–6 mainly include hydroxyl radicals (˙OH), superoxide (˙O 2 −), singlet oxygen ( 1O 2), and hydrogen peroxide (H 2O 2). It would open a new era of pCN for biomedical applications in molecular composite membranes, beyond the traditional solar fuel applications in powders. aureus in sterilization and wound healing for laboratory mice via photogenerated oxygen radicals. Interestingly, the pCN/CNTs molecular composite membrane exhibited not only superior mechanical properties and cycling performance as a result of strengthened π–π interfacial interaction, but also outstanding inactivation of E. Mechanism and generality studies disclosed that the coordination of the acidity, viscosity, and adsorption energy of the solvents led to the successful dissolution of pCN. Herein, we report the dissolution of pCN in polyphosphoric acid (PPA) for the first time and fluid-phase assembly with carbon nanotubes (CNTs) into a flexible free-standing membrane. However, due to poor solubility, compounding pCN at the molecular level into more advanced nanocomposites remains a challenge. Polymeric carbon nitride (pCN) has attracted increasing interest as a metal-free photocatalyst because of its high efficiency in reactive oxygen species (ROS) generation.
