Highly Active, Selective, and Reusable RuO₂/SWCNT Catalyst for Heck Olefination of Aryl Halides

Very fine RuO2 nanoparticles (RuO2NPs) with a mean diameter of about 0.9 nm were decorated on single-walled carbon nanotubes (SWCNTs) by a straightforward “dry synthesis” method. TEM images and the Raman spectrum of the resultant material (RuO2/SWCNT) revealed excellent adhesion and homogeneous dispersion of the RuO2NPs on anchoring sites of the SWCNTs. The surface area of RuO2/SWCNT was found to be 416 m2 g–1. The SEM–EDS results showed that...
