Activated carbon xerogels derived from phenolic oil: Basic catalysis synthesis and electrochemical performances

Abstract: The competitiveness of European coal tar distillation plants could be improved by the revaluation of coal-derived liquids and rejects such as phenolic oils, which currently lack highend applications. In this study, carbon gels were successfully prepared for the first time from phenolic oil by base−catalysed sol−gel polymerisation, by taking advantage of all the major components of phenolic oil rather than the pure, single-component phenolic precursors that are normally used in sol-gel routes. To increase the f… Show more

“…The micropore volume and total pore volume, VDR [cm 3 g -1 ] and V0.97 [cm 3 g -1 ], respectively, were also obtained using the Dubinin-Radushkevich (DR) equation applied to the nitrogen isotherm and the amount of N2 adsorbed at p/p0 = 0.97, respectively. The skeletal density of the carbon materials was determined by helium pycnometry using an AccuPyc II 1340 automatic device (Micromeritics, USA) [73].…”

“…The heating rate was set at 2°C min -1 up to the final temperature of 900°C, which was held for 2h. The latter temperature was selected in order to ensure a high final carbon content [12][13][14]27] and a developed texture, which can be analysed by DFT models that were indeed developed for materials containing quasi-exclusively carbon [72,73]. The carbon gels were named by a letter (A for aerogel, C for cryogel, X for xerogel), followed by the mass of phenolic oil as indicated in the formulations detailed in Table 1.…”

“…Coal tar distillation leads to different fractions, phenolic oil (PO) among them. To the best of our knowledge, there are only two studies dealing with gels and carbon gels based on PO in the open literature [27,28]. A low-value PO from the company Bilbaína de Alquitranes -SA (BASA, Spain), mainly containing phenol, coumarone, o,m,p-xylene, indane, indene, o,m,p-cresol, and naphthalene, has been used in this work as carbon gel precursor.…”
