Tungsten oxide photoactive oxygen species (Reactive Oxygen Species, ROS) refers to highly active oxidizing molecules or ion species that can be produced by tungsten oxide materials under light conditions. These ROS include but are not limited to superoxide radicals (superoxide radical, O2•-), hydroxyl radicals (hydroxyl radicals, •OH), hydrogen peroxide (hydrogen peroxide, H2O2), etc.
When the tungsten oxide material absorbs light energy, its electrons are excited to a high energy level state, forming an excited state tungsten oxide. Subsequently, in the presence of oxygen or water molecules, excited-state tungsten oxide can interact with them, leading to charge transfer and chemical reactions, which in turn generate ROS. These ROS are highly oxidative and reactive, and can interact with biomolecules such as proteins, lipids, and nucleic acids to trigger a series of biochemical reactions.
The generation and activity of photoactive oxygen species in tungsten oxide are of great importance for some applications. For example, in photocatalytic applications, the activity of tungsten oxide photocatalysts is mainly attributed to the generation of ROS, which can participate in the oxidative degradation process of organic pollutants. In addition, tungsten oxide photoactive oxygen species are also used in photodynamic therapy, photosynthesis, sterilization and other fields.
It should be noted that the generation and activity of tungsten oxide photoactive oxygen species are closely related to the properties, structure, surface state and light conditions of tungsten oxide materials. Different tungsten oxide materials and experimental conditions may result in different degrees of ROS generation and reactivity. Therefore, these factors need to be carefully considered and controlled in specific applications to achieve the desired effect of photoactive ROS.
