Ultrasonic irradiation(ultrasonic intensity 78 W/cm2) and low catalyst concentration (C/W = 10 mol/m3) of RF solution are used as an interesting and unique preparation method for 3D interconnected macroporous sonogel (gel irradiated by ultrasound at gelation stage) and/or3D interconnected macroporous carbon monolith without using templates. Keywords: Porous carbon; Pyrolysis; Adsorption; Scanning electron microscopy; Porosity Macroporous monolith is an interesting structure that has interconnected skeletons in a single column, and this unique structure allows flow paths (throughpores)through the monolithic columns . Carbon monolith has high potential to be good candidates for applications such as columns for chromatography, catalyst supports, adsorbents and porous electrodes under continuous flow conditions. Macroporous carbon monoliths are mostly prepared by using carbon precursors and macroscopic shape templates . In general, macroscopic shape templates are interconnected skeleton such as silica template, zeolite, stable emulsions, polymer latex and the interstitial volume of other porous structures. Carbon precursors are polymeric materials or precursor of polymeric materials such as sucrose, some thermoplastics, phenolic resin, copolymerization of resorcinol Fe(II) complex and other thermosettings. There are some reports on macroporous carbon aerogels prepared by using metal catalyst or acid catalyst. In this work, a new method in preparation of 3D interconnected macroporous carbon monolith has been introduced. In general, ultrasonic irradiation has outstanding effects in many chemical reactions such
