Abstract

<abstract> <title> <x content-type="archive" xml:space="preserve">Abstract</x> </title> <sec> <p>Ordered mesoporous carbons (OMCs) with a two-dimensional mesostructure have been synthesised by organic–organic self-assembly of a mixture of poly(propylene oxide)-b-poly(ethylene oxide)-b-poly(propylene oxide) (PPO–PEO–PPO/PEO–PPO–PEO) amphiphilic triblock copolymers as templates, with soluble, low molecular weight phenolic resin precursor through the soft templating method. The hydrophilic/hydrophobic ratios were optimised to obtain OMCs. The microstructure of OMCs was analysed by small angle X-ray scattering, nitrogen adsorption isotherms and transmission electron microscopy. The results showed that the OMCs obtained have uniform pore size distribution centred at ∼3·5 nm with great surface area up to 731 m² g⁻¹ and large pore volume up to 0·44 cm³ g⁻¹. Furthermore, the mesostructure of the OMCs obtained changes from a centred rectangular C2mm to a hexagonal p6mm by tuning the ratios of PEO/PPO.</p> </sec> </abstract>
