Synthesis of ordered mesoporous carbons composed of nanotubes via catalytic chemical vapor deposition

Ordered mesoporous carbons composed of arrays of nanotubes have been synthesized using ordered mesoporous silica templates via catalytic chemical vapor deposition. The ordered carbons possess bimodal pores, namely, the pores arise from the "replica" of frameworks of the template and the pores correspond to carbon nanotubes formed in the channels of the template (see Figure).

A novel approach to Co/CNTs catalyst via chemical vapor deposition of organometallic compounds

A novel approach for attaching well-dispersed cobalt nanoparticles homogeneously onto carbon nanotubes via metal organic chemical vapor deposition technique is reported. The obtained Co/CNTs catalysts feature a narrow size distribution of Co particles centering around 7.5 nm, and show high activity and regioselectivity for hydroformylation of 1-octene.
