MWCNT Characterisation Data.

Supplier	ID	Fe	Co	Ni	Mo	Purity	Diameter (mean)	Length (range)	Zeta Potential	Suspended Agglomeration State
			% of mass				nm	pm	mV	nm
MK Impex	Low Ni-MWCNT	0.054	0.013	2.54	0.1	97.3	33	5–15	−11.3	682

Descriptive Data for Low Nickel and High Nickel-MWCNT (LN-MWCNT and HN-MWCNT) investigated in this study. Median particle diameter and length range of dry material are as described in the methods section. The MWCNT was suspended in DM and sonicated as in the methods section for the agglomeration characterisation. The length of suspended agglomerated particles is unattainable at present time.
