MFI‐type zeolite binderless coating were grown over stainless steel (gauze wire and arranged packing segment) and copper substrates (gauze wire). The kind of preparation and the surface structure (different preliminary treatments of the stainless steel by way of corrosive action) were varied. Four different ZSM‐5‐preparations were selected in consideration of the following aspects: hydrothermal synthesis versus atmospheric pressure, using TPABr as organic template versus template‐free, alkali‐free versus Na 2 O or sodium dihydrogenphosphate, variation of Si/Al‐ratio. In addition, silicalite syntheses were carried out for comparison. The catalytic activity was determined via liquid‐phase hydrogenation reactions. Reactions of interest were the hydrogenation of toluene and the catalytic hydrogenation of dissolved oxygen.
