Abstract (en)

[origin: DE19827844A1] Production of shell catalysts with definite shell thickness on porous ceramic supports comprises coating the support with undecomposed, vaporizable precursors by chemical vapor deposition (CVD) and fixing the metal by simultaneous or subsequent thermal or chemical reduction. An Independent claim is also included for shell catalysts produced in this way.
