Naturforsch. 52c, 639-644 (1997); received May 5/July 3, 1997 Catalase, Immobilized Enzyme, Carbon Materials, Electrochemical and Biocatalytic Activity The adsorption of catalase on two types of soot differing in their structure has been charac­ terized. The adsorption of this enzyme obeys the Tyomkin adsorption isotherm. It has been established that the catalase immobilized on soot and graphite takes part in the electrochemi­ cal oxidation of phenol. The enzyme activity of catalase immobilized on both types of soot was studied on the decomposition of hydrogen peroxide. The kinetic and activation parame­ ters of the processes studied have been determined.
