Synthesizing of helical-single walled carbon nanotubes by chemical vapour decomposition for engine

The captivating interest on carbon nanotubes (CNTs) has kindled the research activity after its discovery
in 1991. It is due to its fabulous properties which have opened numerous applications like high weight to

strength ratio, field emission transistors, and catalysis. Irrespective of the stunning technological devel-
opment there is still much struggle in the synthesis aspect, which is a great drawback in compliance of

these unique materials in the commercial application. Apart from various known method catalytic chem-
ical vapor deposition (CCVD) is more advantages, where SWCNTs can be produced with varying diame-
ters, large scale production, with high purity, variable temperature and most importantly it can be

produced economically. In CCVD technique, We have used magnesium metal as a substrate with transi-
tion metal like Fe, and Ni, to prepare combustion catalyst. SWCNTs synthesized from FeaNibMg1-(a + b)O

(FNM) catalyst had a higher yield than other catalysts with helical structure in the single layer of graphi-
tic carbon (h-SWCNTs). The morphology of the synthesized h-SWCNTs was identified by Field Emission

Scanning Electron Microscope and many others. Environmental damage from industries is looking for a
prominent candidate to sort out the issues such as high catalytic activity, reusability, and stability norms.
With the obtained result a comparative study was done against combustion catalyst, purified and pristine
SWCNTs. It is found that the pristine h-SWCNTs had a good photo catalytic activity with this result wehave confirmed SWCNTs synthesized from solution combustion technique can be utilized for commercialapplication. 2020 Elsevier Ltd.
