An aqueous-phase synthetic route for ruthenium nanoparticles in cellulose nitrate fibres

Ruthenium nanoparticles were prepared in thin membranes made of cellulose nitrate fibres via a straightforward method of impregnation-reduction of metal ions at ambient conditions. TEM and HRTEM results showed that ruthenium nanoparticles were homogenously dispersed in the cellulose nitrate fibres. XPS studies confirmed the influences of the cellulose nitrate fibres functionality for the formation and stabilization of Ru nanoparticles.
