Hydrochloric Acid → 2,6-Dihydroxybenzaldehyde

Mesoporous carbons with highly ordered structure were prepared using weight ratios of 1.1 resorcinol:1.1 F127:0.48 formaldehyde:3.55-8.2 ethanol:5.1-1.67 water:0.16-0.66 HCl. In a typical synthesis, 1.1 g of resorcinol and 1.1 g of F127 were dissolved in 4.5 ml of ethanol (EtOH), and to this was added 4.5 ml of 3.0M HCl aqueous solution and 1.3 g of 37% formaldehyde (37%) was then added. After stirring for 12-13 min. at room temperature, the clear mixture turned turbid, indicating the formation of the ordered nanocomposite and a phase separation. After stirring for a total of 40 minutes, the mixture was centrifuged at 9500 rpm for 4 minutes in order to completely separate and isolate the polymer-rich gel phase. The gel was then loaded on a large Petri dish and cured at 80° C. and subsequently 150° C. for 24 hours each. Carbonization was carried out under nitrogen atmosphere at 400° C. for 2 hours at a heating rate of 1° C./min followed by further treatment at 850° C. for 3 hours at a heating rate of 5° C./min. The produced carbon material is referred to as C-ORNL-1.
