Abstract

Hexagonal shaped nanoporous carbon was synthesized using phenol and formaldehyde in the presence of triblock co-polymer P123 as soft template under hydrothermal reaction at 130 degrees C/24 h, followed by calcination at 700 degrees C for 3 h under N-2 atmosphere. The N-2 adsorption-desorption study revealed the BET surface area of 814 m(2) g(-1) containing micropores and mesopores. The hexagonal morphology of the product of size 100400 nm was revealed by FESEM and TEM. The uniform mesopore arrangement of the particles was confirmed by TEM. For adsorption study with methyl orange (MO), a water contaminant dye, the effect of contact time, adsorbate concentration and temperature on the adsorption capacity of the synthesized product was investigated. The prepared nanoporous carbon showed around 100% of MO adsorption within 20 min with maximum adsorption capacity up to 18.8 mg/g. (C) 2017 Published by Elsevier B.V.
