USE OF TELLURIUM IN CARBON-SUPPORTED, NOBLE METAL-CONTAINING CATALYSTS FOR LIQUID PHASE OXIDATION REACTIONS

摘要

A catalyst comprising a noble metal and tellurium at the surface of a carbonsupport is provided. The catalyst may contain an additional promoter,preferably iron. Also provided are methods for preparing such catalysts andprocesses for the use of such catalysts in liquid phase oxidation reactions,particularly the oxidation of N-(phosphonomethyl)iminodiacetic acid or a saltthereof and the oxidation of formic acid or formaldehyde.
