Advantages
Faster proton transport
Hydrogen-bond regulation optimizes the centroid distance between D-A units to 7.14 Å, balancing electronic coupling and proton transport pathways, achieving a proton conductivity of 0.0126 S·cm⁻¹.
High production rate
Enhanced proton-coupled oxygen reduction kinetics enable a H₂O₂ production rate of 2855 μmol·g⁻¹·h⁻¹ and 43600 μmol·g⁻¹ over 25 h.
Excellent operational stability
The immobilized resin film shows negligible mass loss (<0.42%) during extended operation, indicating excellent operational stability.
Applications
- Photocatalytic H2O2 production：Acts as an efficient photocatalyst to produce H₂O₂ from solar energy and water, replacing the energy-intensive anthraquinone process.
- Proton exchange membranes for fuel cells：With high proton conductivity and film-forming ability, it can serve as a proton exchange membrane or proton transport layer in fuel cells.
- Energy storage electrolytes：Its proton-conducting nature can be utilized in energy storage devices as a proton conductor or electrolyte additive to improve ion transport.
