Abstract: In this work we present, the fabrication of gold nanotube membranes by electroless deposition using porous alumina substrate as a template. Porous anodic alumina oxide (AAO) membranes were prepared by electrochemical anodisation of Al in 0.3 M oxalic acid as electrolyte. This synthesis approach is flexible in providing precise control over the membranes’ pore sizes and lengths. The scanning electron microscopy (SEM) images showed that the pore structure of the AAO template was replicated into gold nanotube (GNT) with numerous gold nanoclusters on the surface. The excellent catalytic properties of the GNT membranes were demonstrated by catalytic conversion of 4-nitrophenol (4-NP) into 4-aminophenol (4-AP) in the presence of NaBH4 as a reductant. The potential for recycling the GNT membrane catalyst was probed and found to be reasonably high with no deactivation effect.
