3D interconnected macroporous carbon monoliths prepared by ultrasonic irradiation

A new method in preparation of 3D interconnected macroporous carbon monolith has been introduced. 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/or 3D interconnected macroporous carbon monolith without using templates.
