“…Attaching noble metal nanoparticles to the surface of CNTs is of interesting to obtain hybrid nanostructure with useful properties [9]. However, since the surface of carbon nanotube is rather inert, activating their surface is an essential prerequisite to attach noble metal nanoparticles to the side wall of CNTs [10,11]. Surface modification of CNTs with organic molecules is a widely used way for anchoring noble metal nanoparticles onto CNTs [12 -14].…”

A novel approach to assemble multilayer films of Pt nanoparticle/multiwalled carbon nanotube (MWNTs) composites on Au substrate has been developed for the purpose of improving the methanol oxidation efficiency by providing high catalytic surface area. MWNTs were firstly functionalized with 4-mercaptobenzene and then assembled on an Au substrate electrode. Pt nanoparticles were fabricated and attached to the surface of the functionalized MWNTs subsequently. Thus a layer of Pt/MWNT composites were assembled on the Au substrate electrode. Repeating above process can assemble different layers of film of Pt/MWNTs composites on the Au electrode. Cyclic voltammetry shows that the Au electrode modified with two layers of film of Pt/MWNT composites exhibits high catalytic ability and long-term stability for methanol oxidation. The layer-by-layer self-assembly technique provides an efficient strategy to construct complex nanostructure for improving the methanol oxidation efficiency by providing high catalytic surface area.

“…Meanwhile, MWCNTs have been regarded as a new support for metal catalysts due to its small size, high chemical/thermal/mechanical stabilities, and large surface area to volume ratio [21][22][23]. However, till today only one investigation has been studied that single-walled carbon nanotubes/polyaniline composite was used to support materials of Pt nanoparticles for HCHO fuel cell [11].…”

Platinum nanoparticles on polyaniline-coat multi-walled carbon nanotubes were fabricated by electrochemical method at paraffin-impregnated graphite electrode (Pt/PAN/MWCNTs). The material was characterized by various methods including field emission scanning electron microscope (FE-SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and electrochemical techniques. The electrode has been effectively applied toward formaldehyde (HCHO) sensing. A good linear response curves from 1 9 10 -9 to 1 9 10 -3 M can be obtained with a lower detection limit of 4.6 9 10 -11 M (S/N 3). The successful preparation of nanocomposites opens a new path to fabricate the promising sensor for HCHO.

Mesoporous Carbon Materials with Ultra‐Thin Pore Walls and Highly Dispersed Nickel Nanoparticles

Mesoporous carbon materials with ultra-thin carbon pore walls and highly dispersed Ni nanoparticles have been successfully prepared by using two different SBA-15 silicas as hard templates and 2,3-dihydroxynaphthalene (DHN) as a carbon precursor. The nickel precursor was a concentrated nickel nitrate hexahydrate [Ni(NO 3 ) 2 ·6H 2 O] solution in 2-propanol, which was added to the carbon-silica nanocomposite prior to thermal treatment. The samples studied were analyzed by thermogravimetry (TG), nitrogen adsorption at -196°C, powder X-ray diffraction (XRD), Raman spectroscopy, scanning and transmission electron microscopy (STEM), and in situ electron diffraction X-ray spectroscopy (EDX). While TG analysis revealed carbon contents lower than 30 wt.-%, nitrogen adsorption provided information about the homogeneity of the carbon thin film deposited onto the mesopore walls of the ordered silica templates SBA-15. The templates, carbon-silica nanocomposites, and carbon inverse replicas with nickel nanoparticles exhibit uniform pores, high surface areas, and large pore volumes. Partially
