“…The usual procedures to prepare porous carbon monoliths are: (i) From carbonization of gels obtained from several carbon precursors and catalysts [1,2,[11][12][13][14][15]18,24,25,29,31], (ii) From carbonization of gels having a "template" that is removed either thermally during carbonization, or chemically by reaction with specific reagents [4,8,23], (iii) From infiltration of an inorganic monolith with a carbon precursor followed by carbonization of the precursor and removal of the inorganic template [8,9,13,30], (iv)…”
