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 carbon support is provided. The catalyst may contain an additional promoter, preferably iron. Also provided are methods for preparing such catalysts and processes for the use of such catalysts in liquid phase oxidation reactions, particularly the oxidation of N-(phosphonomethyl)iminodiacetic acid or a salt thereof and the oxidation of formic acid or formaldehyde.
