Cover Story: Non-magnetic metal Pd nanoparticles are generally not very active for catalytically growing single-walled carbon nanotubes. In this issue, Qin et al. and coauthors propose a “basic support” strategy, where mesoporous magnesia with strong alkalinity is introduced as the carrier material, to improve Pd activity in the heterogeneous catalyst. The charge transfer upshifts the d-band center of Pd, which promotes the chemisorption and dissociation of carbon sources, thus shifting the metal Pd into the “Goldilocks zone” for single-walled carbon nanotube growth. Using carbon monoxide chemical vapor deposition, the magnesia-supported Pd catalyst affords the bulk synthesis of high-quality single-walled carbon nanotubes. Optical characterizations reveal an enrichment of (7, 5) species in the product, which is attributed to their particularly high stability on the Pd catalyst. View this paper
