Green Synthesis of Au-NPs on g-C₃N₄ Hybrid Nanomaterials Based on Supramolecular Pillar[6]arene and Its Applications for Catalysis.

ABSTRACT: Gold nanoparticles (Au NPs) are installed in situ on the surfaces of graphitic carbon nitride (g-C₃N₄) based on supramolecular hydroxylatopillar[6]arene (P6). The Au NPs can be obtained via the redox reaction between HAuCl₄ and P6 without any NH₂-NH₂, NaBH₄, and other reductants, where AuCl₄ ^- is reduced to Au⁰ by the -OH groups in the presence of OH^-, and the -OH groups are oxidized into -COOH. First, P6 is loaded onto the surface of g-C₃N₄ via π-π interaction between P6 and g-C₃N₄, which offers a stabilized and reduced site for in situ anchoring of Au NPs. The hybrid nanomaterial Au-NPs@P6@g-C₃N₄ exhibits higher ca
