A new synthetic route for decorating carbon nanotubes (MWCNTs) with silver nanoparticles by proton beam irradiation at room temperature is presented. Pristine- and surface-modified MWCNTs were comparatively utilized for the preparation of MWCNT-Ag-nanoparticles nanohybrid. Silver nanoparticles on the surfaces of MWCNTs were produced in situ without any additional reducing reagents, and more importantly, all the solutions were aqueous phase-based. The surfaces of MWCNTs were functionalized with thiol groups using several steps, which included an oxidation step. The silver nanocrystals on the surface-modified MWCNTs were spherical and -4 nm in diameter. Thiolated MWCNTs were well decorated with Ag nanoparticles, whereas pristine MWCNTs were not.

“…Therefore, the preparation of well‐defined CNT–Pd nanoparticle composites has been attempted using a variety of electrochemical, chemical, physical, and radiation‐based synthesis methods . Proton beams have been utilized for many applications, but this technology has rarely been used to prepare well‐defined metal nanostructures. In our recent studies, we could demonstrate that morphology‐controlled Au and MWCNT–Ag nanoparticle composites were prepared using a simple proton beam irradiation process under ambient conditions.…”

We present an easy one-pot synthesis route for the production of palladium nanoparticles and multiwalled carbon nanotubes (MWCNTs)-supported Pd-nanomaterial composites by a simple proton beam irradiation process in an aqueous solution at room temperature. Pristine and surface-modified MWCNTs were used to prepare MWCNT-Pd hybrids. Pd nanoparticles on the surfaces of MWCNTs were produced in situ in an aqueous solution without the addition of any harsh reducing agent. Pristine and thiolated MWCNTs were both densely decorated with spherical Pd nanoparticles and eventually Pd nanowire formation on MWCNTs was realized when reaction times exceeded 60 min. The thicknesses of Pd coatings on MWCNT surfaces were controlled by varying the concentration of MWCNTs in the reaction mixture. MWCNT-Pd composites were characterized by time-resolved transmission electron microscopy, selected area electron diffraction, and energy dispersive X-ray spectroscopy, and the results obtained showed that Pd coatings were continuous, and resulted in a MWCNT-supported Pd nanowire structure.

A synthetic route is presented for the high yield production of Au nanomaterials via a simple proton beam irradiation process. We were able to prepare Au nanomaterials under a proton beam at low concentration of cetyltrimethylammonium bromide at room temperature. It was observed that the size and shape of the prepared gold nanocrystals were easily controlled by the dose rate and irradiation time of the proton beam. When the dose rate of the proton beam was kept constant, a shape transition of Au crystals from particles to nanorods/nanowires and then again to particles was observed as the duration time was increased. When the total dose was kept constant by varying the dose rate and duration time of the proton beam, there was an apparent change in the feature size and shape of the Au nanomaterials produced under proton beam irradiation. Once the dose rate reached a proper value, very similar feature shapes of gold nanocrystals were produced, as long as the total dose was constant.
