To be able to produce an SCR catalyst (2), in particular one having a zeolite fraction (Z) as catalytically active fraction, in a reliable process and at the same time achieve good catalytic activity of the catalyst (2), an inorganic binder fraction (B) which is catalytically inactive in the starting state and has been treated to develop catalytic activity is mixed into a catalyst composition (4). The inorganic binder component for the binder fraction (B) is, in the starting state, preferably porous particles (10), in particular diatomaceous earth, which display mesoporosity. To effect catalytic activation, the individual particles (10) are either coated with a catalytically active layer (12) or transformed into a catalytically active zeolite (14) with maintenance of the mesoporosity.

The 3-Glycidoxypropyltrimethoxysilane (GPTMS) decorated magnetic more-aluminosilicate shell Na(Si.sub.2Al)O.sub.6.xH.sub.2O/NiFe.sub.2O.sub.4 structures were hydrothermally prepared and were well characterized by different analysis methods. The XRD patterns were truly proved the formation of the aluminosilicate layer on the surface of the magnetic cores. In addition to the TGA curve which implied on the presence of the GPTMS organic segment, nitrogen adsorption-desorption isotherms demonstrated that the final sample has high specific surface area. The products were incredibly able to remove the toxic lead and cadmium ions from the wastewaters. Furthermore, the mechanism of the sorption and the role of GPTMS in enhancing the sorption capacity of the structures were comprehensively discussed.
