摘要

sonogel-carbon composites and carbon sonogel-modified, a process for their preparation and their application to the manufacture of electrodes and amperometric sensors.; a new process for the preparation of composite materials made of a siliceous matrix and graphite by sol-gel chemistry described.; In this method the sonocatálisis, based on the use of high power ultrasound, on the precursor mixture alkoxide-water in the presence of an acid catalyst but without the use of alcoholic solvent to synthesize a sol is then mixed with graphite is used high purity to form a composite material which is called sonogel-carbon, and that solves the problems associated with volume contraction and excessive porosity of the electrochemical material.
