Gold nanoparticles (Au NPs) are installed in situ on the surfaces of graphitic carbon nitride (g-C 3 N 4 ) based on supramolecular hydroxylatopillar[6]arene (P6). The Au NPs can be obtained via the redox reaction between HAuCl 4 and P6 without any NH 2 -NH 2 , NaBH 4 , and other reductants, where AuCl 4 - is reduced to Au 0 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-C 3 N 4 via π-π interaction between P6 and g-C 3 N 4 , which offers a stabilized and reduced site for in situ anchoring of Au NPs. The hybrid nanomaterial Au-NPs@P6@g-C 3 N 4 exhibits higher catalytic capability than the Pd/C catalyst in 4-nitrophenol (4-NP) reduction and methylene blue degradation, which opens a new avenue for designing more efficient hybrid nanomaterials for application in catalysis, sensing, and other fields.
