Table 1 Characterization properties of CNTs

Sample	BET morphological parameters		TGA: residual weight (%)		XPS at.% O 1 s
	S _BET (m ² /g)	V _mesopores (cm ³ /g) ^a	CNTs	FePcS/CNTs ^b
CNT	90	0.08	1.68	20.66	2.36

^aVolume of mesopores has been calculated by the difference between the volume of N₂ adsorbed at P/P° = 0.9 and P/P° = 0.2.
^bResidual weight of FePcS/CNT composites.
