Composites containing resins and carbon nano-onions as efficient porous carbon materials for supercapacitors.

ABSTRACT: Herein, we report the functionalization of carbon nano-onions (CNOs) with the hydroxyaryl group and subsequent modifications with resins: resorcinol-formaldehyde using porogenic Pluronic F-127, resorcinol-formaldehyde-melamine, benzoxazine made of bisphenol A and triethylenetetramine, and calix[4]resorcinarene-derived using F-127. Following the direct carbonization, extensive physicochemical analysis was carried out, including Fourier transform infrared, Raman and X-ray photoelectron spectroscopy, scanning and transmission electron microscopy, and adsorption-desorption of N₂. The addition of CNO to the materials significantly increases the total pore volume (up to 0.932 cm³ g^-1 for carbonized resorcinol-formaldehyde resin and CNO (RF-CNO-C) and 1.242 cm
