In this work, porous resorcinol–formaldehyde resin (RF) particles were used as support for in-situ preparation of Au nanoparticles (NPs) by directly immersing the RF into the solution of tetrachloroauric acid (HAuCl4). The Au NPs can be deposited on the RF particle surface or inside the RF particles by simply mediating pH of the reaction solutions. It was revealed that the phenolic hydroxyl groups contained in the RF support can act as both ligand and reductant to promote the formation of the Au NPs. Size of the Au NPs deposited inside the RF particles was tunable in the range of 3.7–14.0 nm by changing the concentration of HAuCl4. The Au NPs loaded in RF with optimal size were identified to show balanced activity and stability in catalyzing the reduction of 4-nitroaniline by NaBH4.
