Construction of Multiple Asymmetric Catalytic Sites on Carbon Nitrides Toward Efficient Solar Hydrogen Peroxide Production.

ABSTRACT: Solar-driven hydrogen peroxide (H₂O₂) production represents a sustainable alternative to energy-intensive industrial processes, yet its efficiency is hindered by poor charge separation and sluggish reaction kinetics. Here, a structurally adaptive strategy is proposed to create highly asymmetric multi-active-site architectures by synergistically integrating sulfur (S) dopants and single-atom zinc (Zn) species into the repeating units of 1D and 2D carbon nitride (C₃N₄) frameworks, i.e., C₃N₄ nanotube (CNT) and sheet (CNS). In this structure, S/Zn and N/O atoms contribute to the conduction and valence bands, respectively, providing multiple charge transfer pathways for photogenerated carriers to achieve efficient spatial separa
