ABSTRACT:
An improved catalyst comprising a noble metal and tellurium at the surface of a carbon support is provided. Also provided are novel methods for preparing such catalysts and novel processes for the use of such catalysts in liquid phase oxidation reactions, particularly the oxidation of N-(phosphonomethyl)iminodiacetic acid or a salt thereof.
