From: Tailoring bidirectional electronic transfer interaction tunnels triggers sustainable and high activity of ozone catalysis for water purification

Catalytic ozonation paradigm of typical SACs (A). Conventional SACs lose electrons continuously during catalytic ozonation, resulting in low activity during long-term use. The concept of bidirectional electronic transfer interaction tunnel construction (B). The targeted anchoring of electron-sharing sites furnishes an ample supply of electrons and empty orbitals. This approach paves the way for realizing the concept of sustainable high activity. By establishing bidirectional electron-transport interaction tunnels, electrons can cycle within the catalyst, while simultaneously facilitating the extraction of electrons from contaminants present outside the catalyst.
