...A. Leela Mohana Reddy; M. M. Shaijumon; N. Rajalakshmi; S. Ramaprabhu Multiwalled carbon nanotubes (MWNTs) have been synthesized by the pyrolysis of acetylene using hydrogen decrepitated Mischmetal based A B 3 alloy hydride catalyst. Structural, morphological, and vibrational characterizations have...

.... DKKK powders have been manufactured using a wet coprecipitation chemical route, and Praxair powders have been produced by spray pyrolysis. The morphology of the powders, as studied by scanning electron microscopy, has been very different. DKKK powders were presented as soft ( ∼ 100 μ m ) spherical...

... convenient physical and chemical properties to be employed as a support for electrocatalysts. MWCNTs were synthesized by spray pyrolysis using a precursor solution of ferrocene dissolved in benzene or toluene. Ammonium hexachloroplatinate, ammonium hexachlororhutenate, and ammonium hexachloropaladate were...
