Abstract
Porous carbons (BSPCs) were obtained by carbonization of resorcinol-formaldehyde gels in the presence of cationic surfactants mixture (benzalkonium chloride) which act as porosity stabilizer. The application of an inexpensive industrial grade surfactant mixture as porosity stabilizer permits obtaining porous carbons with well-developed micro and mesoporosity at low cost. The stabilizing effect on the sol
