Abstract

We report an efficient method for anchoring Pt clusters (e.g., 6 nm in size) on the surfaces of N-doped multi-walled carbon nanotubes (MWNTs-CN_x) using a relatively simple method consisting of a hydrothermal treatment of Na₂[PtCl₆] · 6H₂O and N-doped nanotubes dispersed in acetic acid. The catalytic properties of this material were evaluated finding that the conversion of cinnamaldehyde using Pt-coated MWNTs-CN_x could increase up to 6 times with respect to that obtained for uncoated MWNTs-CN_x and pure carbon CNTs. Therefore, we envisage this material could be either used as an efficient catalyst or as a sensor.
